The Fascinating Truth About Gravity | Jim Al-Khalili: Gravity and Me | Spark


From the award-winning team that brought you The Secret Life of Chaos comes a unique television event on the physics of gravity, featuring unexpected historical insights, cutting-edge science and exciting new experiments.

With the brilliant Professor Jim Al-Khalili as our host, we visit the LIGO lab in the USA where gravity waves were discovered and uncover the latest theories about our cosmos that have come from studying the most intense sources of gravity imaginable – black holes.

Elsewhere, Jim even uses Albert Einstein’s theories of special and general relativity to work out how the rate at which you age is affected by gravity and the speed at which you move about.

The Physics of Car Crashes


How is the chemical energy of gasoline transformed into kinetic energy of a moving car? And where does that kinetic energy go when the car crashes into something and stops moving?

A Brief History of Timekeeping | How Humans Began Telling Time | EXPLORE MODE


#Timekeeping #History #ExploreMode
A lot goes on in just 24 hours. But why is a day divided in 24 hours in the first place? Who decided how we would calculate it?

Today, time is tucked away in our pockets, just an unlock button away. It drives our technology, with atomic clocks being responsible for precise GPS location services and speedy internet search results.

Our ancestors, on the other hand, didn’t have it that easy. Time for them was written in the stars, in the sunrise and sunset, in the moon’s waning and waxing.

So how did we go from looking up to celestial bodies to looking down at our phones for time? What other timekeeping methods did ancient humans use before watches and clocks became ubiquitous? And what the heck is an atomic clock?

You’re watching Explore Mode and today, we are diving into time, and how humans developed technologies to measure it.

Параллельные миры, квантовая механика и кот [Veritasium]


Помощь проекту: vertdider.tv/to-support-us/

Сколько раз вы пытались понять квантовую механику? А сколько раз получилось? Наконец за объяснение взялся Дерек Маллер. Из видео узнаем, что там с параллельными мирами, сколько их может быть и еще раз попробуем вникнуть в то, что такое суперпозиция и квантовая запутанность.
