KNOW WHY CRICKETERS USE WHITE POWDER DURING MATCH !

One of the things we've always been curious about is the white cream that cricket players use on their faces. 

Zinc oxide is the white cream that many cricketers use on their faces. Zinc oxide is a physical sunscreen that rests on top of the skin and is known as a reflector. It creates a thick protective coating that helps to deflect the sun's damaging UVA and UVB rays away from the skin. 

Chemical sunscreens, often known as absorbers, are the ones you use every day. These absorb into the skin, allowing UVA and UVB rays to pass through the top layer before being dealt with under the surface. Because cricketers might be exposed to direct sunlight for up to 6 hours during a game, they utilize zinc oxide. Playing five days in a row in the sun is not a simple task during a Test match, and since the players are taking every care to keep healthy, it is critical to pay attention to minor details.

This much sun exposure may be dangerous, therefore protecting your skin with a reflecting physical sunscreen like Zinc oxide on vulnerable regions is the safest method to avoid skin damage. Zinc creams, even colored ones, are effective because a thick coating of the cream filters all UVA and UVB rays, ensuring that ears, noses, and cheeks are protected.   

Compared to traditional chemical sunscreens, zinc oxide has a number of advantages:

Zinc oxide gets to work right away. The majority of chemical sunscreens advocate waiting 20 minutes after application before going outside in the sun. When it comes to zinc oxide lotion, you're good to go as soon as you apply it. It's gentle enough for even the most delicate skin. Chemical sunscreens, on the other hand, might irritate the skin. Zinc oxide can aid in skin healing and irritation reduction. Thank you for taking the time to read this article, hope you found it useful.

KNOW WHY AIRPLANES DO NOT FLY OVER THE PACIFIC OCEAN !

There are some exceptions, though the majority of commercial airlines do not offer flights directly across the Pacific Ocean between the United States and Asia. They prefer curved pathways that go through landmasses instead. You might ask why commercial planes do not fly directly across the Pacific Ocean if you are not familiar with commercial flights. Let's answer this in the following article.

Planes do not fly over the Pacific because curved routes are shorter than straight routes. Straight roads may not necessarily provide the shortest route between two locations. For any commercial airline, a curved route will give the fastest and most fuel-efficient trip. If you want, try an experiment with a globe. Locate two places on the globe. Link a length of rope to show a straight route, draw a line between these two points. When you're done, draw a line across the rope at this distance with a marker. Now it's time to work out the length of a curved line that connects the same two points. Use the same rope to connect the two spots using a curved route. Try this and you will see that the curved way is shorter than the straightway.

Commercial airlines frequently travel along with a northern curving pattern between Alaska and Canada. It leads to a shorter route, which saves time.

Another reason is jet streams, which are a group of air currents circling the Earth many miles above the surface of Earth. These air currents generally migrate west to east due to the Earth's rotation. When you are flying in the same direction as a jet stream, it helps an airplane save fuel and time.

So these are the basic reasons for planes not flying over the pacific ocean. Thank you for reading the article. 

KNOW THE MEANING OF U/A, U, A, AND OTHER CERTIFICATIONS GIVEN TO MOVIES IN INDIA !

All movies in India open with a black-and-white page with a lot of text on it. And you must have noticed, this page always has a capital U, A, or a UA at it top right corner. Have you thought of what do these letters mean? Let's discuss the whole background about this in the following article.

This page is the mandatory Film Certificate that is issued by the Censor Board of Film Certification (CBFC). The CBFC categorizes the film into U, UA, A, and S.

The 'U' - Stands for 'Unrestricted/ Universal', which means everybody is permitted to watch the film.

The 'UA' - Stands for 'Unrestricted with Caution/ Parental Guidance', which means parental guidance is required for viewers under the age of 12.

The 'A' - Stands for 'Adults Only', which obviously prohibits anybody under the age of 18 to watch the film in theatres.

The 'S' - Stands for 'Restricted to special classes', which means only certain members of the society, such as doctors, scientists, etc, are permitted to watch the film.

Apart from the above categories, V/U, V/UA and V/A- are for the parts of the video released from the film with specific certificates.

The certificate (Part 1) must be displayed on the screen for a minimum of 10 seconds before the movie begins. If there is a Part 2 of the certificate, which is a list of the cuts suggested in the movie, it must be displayed in the theatre where the movie is playing. In fact, both parts of the certificate must be "prominently" displayed in the theatre lobby.
