​​What is Lightning?

Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground. When the opposite charges build up enough, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning. The flash of lightning temporarily equalizes the charged regions in the atmosphere until the opposite charges build up again.

Lightning can occur between opposite charges within the thunderstorm cloud (intra-cloud lightning) or between opposite charges in the cloud and on the ground (cloud-to-ground lightning).

Lightning is one of the oldest observed natural phenomena on earth. It can be seen in volcanic eruptions, extremely intense forest fires, surface nuclear detonations, heavy snowstorms, in large hurricanes, and obviously, thunderstorms.
Most, if not all, lightning flashes produced by storms start inside the cloud. If a lightning flash is going to strike ground, a channel develops downward toward the surface. When it gets less than roughly a hundred yards of the ground, objects like trees and bushes and buildings start sending up sparks to meet it. When one of the sparks connects the downward developing channel, a huge electric current surges rapidly down the channel to the object that produced the spark. Tall objects such as trees and skyscrapers are more likely than the surrounding ground to produce one of the connecting sparks and so are more likely to be struck by lightning. Mountains also make good targets. However, this does not always mean tall objects will be struck. Lightning can strike the ground in an open field even if the tree line is close by.

​​What are contact Lenses made of?

There are three main categories of contact lenses, based on the materials they are made of: soft contacts, rigid gas permeable (GP) contacts, and hybrid contact lenses.
Soft contacts are made of pliable hydrophilic ("water-loving") plastics called hydrogels.

Hydrogels absorb significant amounts of water to keep the lenses soft and supple.
Because of this water-loving characteristic, the water content of various hydrogel contact lenses can range from approximately 38 to 75 percent (by weight).

The water content of soft lenses allows oxygen to pass through the lenses and keep the cornea healthy during contact lens wear.

Gas permeable contacts, also called GP or RGP lenses, are rigid (hard) contact lenses. Like hydrogels used for soft lenses, materials used to create GP contact lenses also are "gas permeable," allowing oxygen to pass through the lenses to the cornea.

Unlike soft lenses, however, rigid gas permeable lenses do not contain significant amounts of water. Instead, GP lenses rely on their microscopically porous nature to transmit oxygen to the cornea.

Hybrid contact lenses have a rigid GP central optical zone, surrounded by a peripheral fitting zone made of a soft contact lens material.

​​Why does your Stomach growl when you are hungry?

The growling sound you hear from your stomach when you're hungry is known as "borborygmi" (singular: borborygmus). It is a normal physiological response that occurs as a result of the movement and contraction of the muscles in your gastrointestinal tract.

When you haven't eaten for a while, your stomach and intestines go through a process called the migrating motor complex (MMC). The MMC is a cyclical pattern of contractions that helps move residual food particles, gas, and digestive secretions along the digestive system.

During the fasting phase, which occurs between meals or when you haven't eaten for some time, the MMC becomes more active. These contractions can create the rumbling or growling noises you hear.

The growling sounds are caused by the movement of gas and fluid in your intestines, as well as the contraction of muscles in the stomach and small intestine. The contractions can be quite forceful, and when they occur in the presence of air and fluid, they produce the characteristic rumbling sound.

It's important to note that borborygmi are not exclusive to hunger. They can also be caused by other factors, such as gas or the movement of stool through the digestive system. Additionally, some individuals may experience more noticeable stomach growling than others, even when they are not necessarily hungry.

​​What is the difference between Sugar Free, No Sugar Added, and Unsweetened?

Reading food labels can be tricky, especially when all the words sound like they mean the same thing. When you're grocery shopping and you see labels with "sugar free," "no sugar added," and "unsweetened," it may seem like you can buy any one of those products interchangeably. But each of those labels means something a little different.
The terms "sugar-free," "no sugar added," and "unsweetened" are often used on food and beverage labels to indicate different levels of sugar content or sweeteners. Here's an explanation of the differences between these terms:

Sugar-Free: "Sugar-free" means that the product contains no added sugars or sugar-based sweeteners. However, it's important to note that "sugar-free" doesn't necessarily mean the product is completely devoid of sweetness. Sugar alcohols or artificial sweeteners may be used as sugar substitutes to provide a sweet taste without adding actual sugar. It's crucial to check the ingredients list to see if any sweeteners or sugar substitutes are present.

No Sugar Added: "No sugar added" means that no additional sugars or sugar-based sweeteners have been added during the manufacturing process. However, the product may still contain naturally occurring sugars, such as those found in fruits or dairy products. It's important to read the nutrition facts label to determine the total sugar content and differentiate between naturally occurring sugars and added sugars.

Unsweetened: "Unsweetened" means that no sweeteners, including both natural and artificial sweeteners, have been added to the product. It indicates that the food or beverage is in its natural state without any added sweetness. However, it's essential to note that the product may still contain naturally occurring sugars, depending on the ingredients used.

When making dietary choices, it's important to consider individual dietary needs and preferences. If you're looking to reduce sugar intake, it's beneficial to read nutrition labels carefully and pay attention to the ingredients list to identify any hidden sugars or sweeteners that may be present. Additionally, it's advisable to consult a healthcare professional or registered dietitian for personalized guidance on sugar consumption and overall dietary choices.

​​What is Gesture Recognition Technology and How Does It Work?

As the name suggests, gesture recognition is designed to recognize the physical movements, or “gestures,” of humans.

Waving your hand in a particular pattern in front of the device, for instance, may tell it to launch a specific app.

Gesture recognition such as this is often found in smartphones and tablet computers. 

Gesture recognition is classified as a type of touchless user interface (TUI). Unlike a touchscreen device, TUI devices are controlled without touch. A voice-controlled smart speaker like Google Home and Amazon Alexa are prime examples of TUIs.

By speaking commands, you can control these devices, all without relying on touch.

However, gesture recognition is also a type of TUI, as it’s also controlled without the use of touch.

With that said, many devices that support gesture recognition also support touchscreen.
While there are many different types of gesture recognition technology, they all work on the same basic principle of recognizing human movement as a form of input.

The device features one or more sensors — or cameras — that monitors the user’s movement. When it detects a movement that corresponds with a command, it responds with the appropriate output.

This may be unlocking the device, launching an app, changing the volume, etc.

​​How does Soap and Detergent work?

Soaps and detergents are made from long molecules that contain a head and tail. These molecules are called surfactants; the diagram below represents a surfactant molecule.

The head of the molecule is attracted to water (hydrophilic) and the tail is attracted to grease and dirt (hydrophobic). When the detergent molecules meet grease on clothes, the tails are drawn into the grease but the heads still sit in the water.
The attractive forces between the head groups and the water are so strong that the grease is lifted away from the surface. The blob of grease is now completely surrounded by detergent molecules and is broken into smaller pieces which are washed away by the water.
The detergent molecules also help to make the washing process more effective by reducing the surface tension of the water. Surface tension is the force which helps a blob of water on a surface hold its shape and not spread out. The attractant molecules of the detergent break apart these forces and make water behave, well, wetter!

​​What are the importance of Foundation in building construction?

A strong and well-designed foundation is essential for any building construction for several reasons:
Structural Integrity: The foundation serves as the base on which the entire building structure rests. A strong foundation helps to distribute the weight of the building evenly, providing stability and ensuring that the building remains standing during natural disasters or ground movements.
Stability: A sturdy foundation ensures that the building remains stable and level. This is particularly important in areas prone to earthquakes, floods, or landslides, where a weak foundation can cause the building to collapse or shift.
Prevents Settlement: A well-built foundation helps to prevent settlement or sinking of the building, which can lead to structural damage or cracks in the walls and foundation.
Longevity: A good foundation can help to extend the lifespan of the building, preventing premature decay, and reducing the need for costly repairs.
Building Code Compliance: Building codes require that all buildings have a foundation that meets specific criteria. A properly designed and constructed foundation ensures that the building meets these requirements, ensuring compliance with the code.
A foundation is crucial in building construction as it provides structural integrity, stability, prevents settlement, increases longevity, and ensures building code compliance.

​​What Is Glare?

When a bundle of light hits a flat surface, it becomes polarized, or is reflected horizontally.  The bundle becomes concentrated and is blinding anyone observing it. This is referred to as blinding glare.

These reflections can be uniform, which is light reflected from a smooth service. Uniform reflections would be light reflected off the road, or off a car’s bumper or back window. They can also be non-uniform, which is light reflected from an uneven surface. An example of this would be light reflected off running water or a patch of ice on the road.

No matter what the case, the desired result is to filter out the distracting reflected light and provide a clear viewing experience for the wearer.

​​What is the function of Earwax in the Human Body?

The earwax is very useful substance which keeps our ears healthy and is produced naturally in the ear. This wax is found not only in humans, but also in animals. It cleans, protects and lubricates the ears. Let us study through this article about earwax, its function etc.

The scientific name of the earwax is cerumen. It is formed in the outer part of our ear canal where there are thousands of glands. It is sticky and shiny substance. It coats the ear to moisturize it and fight against infection. Earwax also prevents from dust, dirt, and insects from entering the ear.

It also works like a natural antibiotic, i.e. it contains anti-microbial properties. According to some researchers, cerumen contains a lysozyme antibacterial enzyme which is capable of destroying the walls of the cells of bacteria.

With the help of earwax, you can tell which family you belong to. People have wet or dry wax. Although, both the wax is made up of chemicals. But it depends upon the family that the wax will be wet or dry in your ear. This is detected by the gene. This gene is called ABCC11. If the gene G is replaced by gene A, then, the wax in the ear will be dry and its odour will also be different.

Earwax works by: Protecting and moisturizing the ear canal skin, Preventing dry & itchy ears, Utilising special chemicals that help ward off ear infections. Shielding the eardrum. Trapping dust, dirt, water and other things that can enter your ear, so they don’t travel any further. Earwax is essential to good ear health. However, build-up can easily be problematic for your overall quality of hearing.

​​How does Digital Thermometer Work?

Digital Thermometers are slowly replacing the conventional mercury thermometer due to the ease of taking reading. People often have the misconception that it contains mercury. Digital Thermometers are mercury free. These thermometers contain thermistor inside the tip which is used to measure the temperature. They provide quick and highly accurate results over the body temperature range.

These thermometers are easy to read with LCD display on them. They are equipped with beep alarm & memory function and can record a wide range of temperature. Doctor’s thermometer which are mostly used can read temperature between 94oF and 105oF (35oC and 42oC). It is three in one thermometer as it can record oral, auxiliary and rectal temperatures.

The tip is said as the heart of the thermometer. It is the placed closed to the body part to measure the temperature of the body. The tip of the Thermometer contains thermistor to measure temperature. It is a ceramic semiconductor which is bonded in the tip with temperature sensitive epoxy. It is covered with a cap so to prevent it from the outer world. The cap may be made up of metal or stainless steel. Thermistor is responsible for converting the physical temperature into electrical signals.

Thermistor is a special kind of semiconductor in which the value of resistance changes with the change in temperature. Due to change in resistance value, the output voltage changes and the temperature change is detected.

​​What purpose do Reflectors serve in Photography?

A Reflector refers distinctly to an equipment used by photographers and cinematographers to bounce light in a certain direction. It acts as a medium to bounce light and redirect light to illuminate the subject more effectively! A reflector can be either artificial or natural, natural reflectors are objects in the environment that naturally reflect light - cars, walls, buildings, roads and other reflective surfaces are natural reflectors.

Artificial reflectors are used by photographers to control the brightness and intensity of available light and to counteract harsh over exposure due to available light. The artificial reflector is made up of two parts, the reflective material and the frame. The purpose of the frame is to keep the reflective material taught at an angle that directs the reflected light to a specific direction.

There are many different reflective surfaces used, the most common being, white, silver and gold. Depending on the specific reflective material used, a different effect is achieved by varying the distance from the subject and angle of reflected light. Black colored reflectors are used to absorb light and introduce shadows.

Reflectors empower the photographer to control the quality of light and also gives them control over the overall contrast and shadows created by reflecting natural or artificial light from a light source. An additional use of reflectors is when it is coupled with a studio strobe. it varies the angle at which the light is emitted out. Reflectors vary in size and shape and depending on the particular need of the photographer or cinematographer to light a scene, a particular type of reflector is used.

​​What’s the difference between Optical Zoom and Digital Zoom?

Zoom is a term that is often used in photography which signifies a change in the apparent distance between the camera and the subject.

Zooming in photography is generally of two main types optical zoom and digital zoom. Both the methods use different technologies and produce different qualities in the results.

The main difference between optical zoom and digital zoom is that optical zoom involves a physical camera lens movement, which changes the apparent closeness of the image by altering its focal length whereas in digital zoom, the pixels are enlarged at the center of the screen and the scene being clicked is magnified.

Optical zoom is caused by the physical movement of the lens of the camera. It helps to magnify the scene without affecting the quality of the photo.

Optical zoom provides clearer and zoomed photos.

Optical zoom works by altering the focal length of the lens, thus bringing the image closer.

On the other hand, digital zoom is a type of inbuilt processing software in the camera that the user can use to zoom in after the picture has been clicked.

It is done by enlarging the pixels in the center of the screen therefore it causes a decrease in the quality of the image and less resolution.

​​What Is Difference Between Whey Protein And Whey Isolate?

When searching for protein powders, you may have encountered the whey protein vs whey isolate debate. Whether you're looking to build muscle or you’re after the best protein powder for weight loss, you'll come across these two whey-based proteins a lot. Both come from dairy; whey is a byproduct of cheese production. But there are several differences between the two.

Whey isolate is just whey protein but with the lactose, a sugar commonly found in dairy, removed. As a result, whey isolate tends to have a lower fat and calorie content and a higher protein intake per serving than whey protein, which has a higher calorie and fat content due to the lack of additional processing.

Whey isolate tends to have a slightly higher protein content than simple whey protein powder, as the process which removes the lactose from the powder also concentrates the protein somewhat.

Whey isolate tends to have a lower calorie, carbohydrate and fat count, which makes isolate ideal for mixing with water for a low-calorie, high-protein drink. Great for building lean muscle. Whey protein is still a very efficient way to cram more protein into your diet, whether you’re making shakes or pouring scoops of the stuff into pancake mix, oats or your morning yoghurt. However, it does come loaded with a few extra calories.  

If you’re just after a drink to add more protein to your diet without additional calories, fat or triggering any digestive issues with lactose you may have, whey isolate is what you’re after. However, whey protein, as a more common supplement, is often seen on offer and at far greater varieties of flavour.

​​What is Digital Signature?

A digital signature is a cryptographic technique used to verify the authenticity, integrity, and non-repudiation of digital documents or messages. It provides a way to ensure that a digital document or message has not been tampered with during transmission and that it originated from the expected sender.

Here's how digital signatures work:

Hashing: The first step in creating a digital signature is to generate a unique hash value for the document or message. A hash function takes the input data and produces a fixed-size string of characters, called a hash value or message digest. Even a small change in the input data will result in a significantly different hash value.

Private Key Encryption: The hash value is then encrypted using the sender's private key. The private key is a part of a cryptographic key pair, consisting of a private key and a corresponding public key. The private key is kept secret and known only to the sender.

Digital Signature: The encrypted hash value, along with the original document or message, forms the digital signature. It is appended to the document or message and can be transmitted along with it.

Verification: To verify the digital signature, the recipient uses the sender's public key to decrypt the encrypted hash value. If the decrypted hash value matches the hash value computed from the received document or message, it indicates that the document or message has not been altered during transmission and that it originated from the expected sender.

Digital signatures provide several benefits:

Authentication: Digital signatures provide proof of the identity of the sender. The recipient can verify the signature using the sender's public key, ensuring that the document or message was signed by the claimed sender.

Integrity: Any modification to the signed document or message, intentional or accidental, will result in a different hash value, rendering the signature invalid. Thus, digital signatures protect the integrity of the data by detecting any changes made.

Non-repudiation: Digital signatures provide non-repudiation, which means that the sender cannot deny sending the document or message. Since the signature can only be created with the sender's private key, it serves as evidence of the sender's intent.

Tamper Detection: If someone tries to tamper with the document or message during transmission, the signature verification will fail, indicating that the data has been altered.

Digital signatures are widely used in various applications, such as secure email communication, software distribution, financial transactions, contracts, and legal documents. They play a crucial role in ensuring the security and authenticity of digital communications and transactions.

What is the link between climate crisis and meat/dairy products?

The link between climate crisis and meat/dairy products may not be obvious, but for many experts it’s clear.

🥩🥛↔️🌏🌦
Studies affirm that between 11.1 and 19.6% of global human-made greenhouse gas (GHG) emissions come from meat and dairy production/animal agriculture, which is a leading cause of deforestation, responsible for significant biodiversity loss and pollution, and emits large amounts of methane, which alone is the cause of over 25% of global warming.

📌Some experts even claim that animal agriculture is the largest contributor to global climate change.

📌However, according researchers, the extent to which it contributes to global emissions depends on how studies define different economic sectors, and whether they incorporate farming equipment and food exports in the assessment of animal impact.

ℹ️Most sources list animal agriculture as the No. 2 contributor to GHG emissions after fossil fuels.

​​How does Graphene coating improve a car's appearance?

Graphene coating can improve a car's appearance in several ways.

First, graphene is a highly durable and transparent material, which means that when applied as a coating on a car's surface, it can provide long-lasting protection against scratches, chips, and other types of damage that can affect a car's appearance.

This can help keep the car looking newer and more attractive for a longer period of time.

Secondly, graphene coatings can create a hydrophobic effect on the car's surface, which means that water and other liquids will bead up and roll off the surface instead of sticking to it.

This can help prevent water spots and stains from forming, which can make a car look dull and dirty.

Additionally, graphene coatings can enhance a car's shine and colour depth, giving it a more vibrant and lustrous appearance.

The ultra-smooth surface of the graphene coating can reflect light more effectively, which can make the car's paint job look brighter and more vivid.

Finally, because graphene is a nanomaterial, it can be applied in very thin layers, which can make the car's surface feel smoother to the touch. This can create a sleek and polished look that enhances the overall appearance of the car.

What is the greenhouse effect and why is it important?

✅ The greenhouse effect
is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.

✅ Scientists have determined that carbon dioxide's warming effect helps stabilize Earth's atmosphere. Remove carbon dioxide, and the terrestrial greenhouse effect would collapse. Without carbon dioxide, Earth's surface would be some 33°C (59°F) cooler.

✅ Greenhouse gases occur naturally and are part of our atmosphere's makeup. For that reason, Earth is sometimes called the “Goldilocks” planet – its conditions are not too hot and not too cold, but just right to allow life (including humans) to flourish. Part of what makes Earth so amenable is its natural greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average.

​​​​How does a Ball Point Pen work?

A Ball point pen is a pen that uses a small rotating ball made of brass, steel, or tungsten carbide to disperse ink as you write. All of the pens that preceded the ballpoint -- whether quill, metal or fountain -- used a watery, dark india ink that fed through the pen using capillary action. The ink can flow unevenly.
The ball is located in between the ink reservoir and the paper by a socket, and while it's in tight, it has enough room to roll around as you write. As the pen moves across the paper, the ball turns and gravity forces the ink down the reservoir and onto the ball where it is transferred onto the paper. It's this rolling mechanism that allows the ink to flow onto the top of the ball and roll onto the paper you're writing on, while at the same time sealing the ink from the air so it does not dry in the reservoir.

​​What is a Heart Murmur? What are some common reasons that Heart Murmurs occur?

Doctors listen to heart sounds by stethoscope. Normally heart sounds like "lub-dup". So there are two sounds : first heart sound (S1) and the second heart sound (S2). Sometimes a water flow like (whooshing or swishing) sound accompanies the "lub-dup". This is called heart murmur.

Heart murmurs are produced by turbulent blood flow across an abnormal heart valve, septal defect of heart or outflow obstruction from heart; or they may be produced by increased volume or velocity of blood flow through a normal heart valve.

Murmurs are produced both in normal and abnormal heart. Heart of pregnant woman and athletes may produce murmurs. These are the examples of "Innocent murmurs".

Other causes of heart murmur are : Valvular heart diseases (mitral stenosis and regurgitation, tricuspid stenosis and regurgitation, aortic stenosis and regurgitation, pulmonary stenosis and regurgitation), Patent ductus arteriosus, ventricular septal defect etc.

​​What is an Orthopaedic Shoe?

Orthopedic shoes, also known as custom-made therapeutic shoes, are designed for patients with significant deformities. They are made to fit specifically to their morphology. This equipment aims to improve the functions of walking, particularly thanks to the orthopedic insoles called plantar orthoses.

Orthopedic shoes feature orthotic insoles that provide good arch support. The main purpose of the arch support is to eliminate excessive pronation, which affects foot function and is the main cause of foot and heel pain.

Orthotic insoles help reduce pressure on the heel and the ball of the foot by transferring a substantial portion of body weight to the arch. In shoes without good arch support, the arch area doesn’t participate in distributing the pressure under the foot.

Excessive pronation causes the leg to internally rotate, putting stress on the knee, hip and lower back. Orthotic insoles with good arch support play an important role in alleviating stress on the knees, hips and lower back as well in improving foot and leg alignment.
