Extreme Cold Warning in the United States: The Science Behind the Deep Freeze Introduction As temperatures plummet across the United States, extreme cold warnings have gripped large portions of the country. The bone-chilling cold isn't just inconvenient—it's dangerous, affecting millions of lives and disrupting daily activities. But what causes such extreme cold spells, and how does science explain these phenomena? Let’s delve into the meteorological and scientific reasons behind these frigid temperatures. What is an Extreme Cold Warning? An extreme cold warning is issued when temperatures or wind chill values are so low that they pose a risk to public safety. Frostbite, hypothermia, and other cold-related illnesses become real threats in these conditions. The thresholds for such warnings vary depending on the region but are typically issued when the wind chill drops to dangerous levels. The Science Behind the Arctic Chill Polar Vortex The primary driver of extreme cold in the...

How to Improve Your Lifestyle and Stay Positive? These are some methods with which you can improve your lifestyle. If you are applying less than 5 one of these methods then your life is not going well you should check this out. Good night’s sleep Advice from sleep scientist  Prof Alice Gregory   at Goldsmiths, University of London © Eva Bee If you can’t sleep, get up and do something different It’s normal to wake up during the night, but most people just fall straight back to sleep without realising it. If you can’t get back to sleep easily, or if you struggle to nod off in the first place, don’t just lie there. Get up and do something else. It’s important to associate bed with sleep and not with being mentally awake. Stick to consistent bedtimes and waking times – yes, even at the weekend! Stick to a routine with a consistent bedtime and waking time. Your body needs to know what it should be doing and when it should be doing it. This is important for all of us, including babi...

What is Li-Fi technology?

Li-Fi(Light fidelity) Technology Li-Fi is called internet at the speed of light . LiFi technology will allow us to connect to the internet using light from lamps, streetlights or LED televisions. In addition to being cheaper, safer and faster than wifi, it does not need a router. All you need to do is point your mobile or tablet towards a light bulb to surf the web.   WHAT IS Li-Fi TECHNOLOGY? LiFi (light fidelity) is a bidirectional wireless system that transmits data via LED or infrared light. It was first unveiled in 2011 and, unlike wifi, which uses radio frequency, LiFi technology only needs a light source with a chip to transmit an internet signal through light  waves. This is an extraordinary advance over today's wireless networks.  LiFi multiplies the speed and bandwidth of wifi, 3G and 4G.   The latter have a limited capacity and become saturated when the number of users surfing increases, causing them to crash, reducing speeds and even interrupting the...

What is Hawking Radiation? To put it simply: It’s the radiation emitted from a Black Hole and it was, as the name suggests, discovered by Stephen Hawking. History is not everything but its a start! -John Henrick Clarke So, let’s see what history has in store for us… It all started in 1972 when Jacob Beckenstein theorized that Black Holes should have  Entropy.  So, maybe you’re asking yourself… What is Entropy? Entropy is a part of thermodynamics and it basically states that Everything must release heat. Unless it is at 0 degree kelvin( -273 degrees celsius). Now this includes a Black Hole.  But as we’ve known that black holes have always appeared to absorb things! It never releases things… Even the light coming out undergoes a high degree of redshift due to which the frequency falls below the visible spectrum! But Jacob thought that there should be some heat still leaving it according to Thermodynamics! This led Stephen Hawking, in 1973, to go to Moscow to meet 2 Soviet S...
