For such a short amount of time, this video really left my wowed. I love illustrations to go with explanations during the process of teaching something new and foreign, so you can only imagine how crazy I went for this video. I even watched the other videos on their channel for MinutePhysics and even though the topics may seem "boring" or "too hard," I had no trouble keeping up with the pace of the videos and I have such a miniscule knowledge of physics. I'm not really sure how else to explain how much I enjoyed watching this video, it was extremely fun and creative and I wish I could learn everything this way, because it feels like I'm making it happen in a way and we're learning together, if that makes any sense. This was a pretty tricky subject and I loved how at the end he threw in a little bit about parallell universes and my brain just tipped over the edge to explosion. These spurts of information are definitely slightly overwhelming, but it makes you feel like you learned a lot in only two or three minutes, and I recommend anyone to watch them if they're feeling a little existential or just curious about the universe!

How can you create a universe from nothing? Well if you calculate the total matter of the universe it is positive. If you calculate the total energy of the universe it is negative because of gravity. Gravity has negative energy. When you add the two together what do you get? Zero, so it takes no energy to create a universe. Universes are for free. A universe is a free lunch.

Have you ever stopped to ask yourself, "what is time?" We all understand its passage intuitively, experientially. But does time actually exist? Is it a force of nature? A tangible entity? I spoke with theoretical physicist and perhaps the world's premier expert on the science of time, Sean Carroll, to learn more.

When artist David Alfaro Siqueiros first discovered his "accidental painting" technique in the 1930s, the simplicity of the process coupled with its elaborate results riveted him.

Why should you bother to wake up tomorrow knowing that we're all going to die billions and billions of years from now when the universe turns to absolute zero, when the stars blink out, when we have nothing but neutron stars and black holes? Dr. Kaku says that billions of years from now we may be able to move to a different universe.

Paul Davies, a British-born theoretical physicist, cosmologist, astrobiologist and Director of the Beyond Center for Fundamental Concepts in Science and Co-Director of the Cosmology Initiative atArizona State University, says in his new book The Eerie Silence that any aliens exploring the universe will be AI-empowered machines. Not only are machines better able to endure extended exposure to the conditions of space, but they have the potential to develop intelligence far beyond the capacity of the human brain.

What is the simplest, most fundamental clock? UC Berkeley physicist Holger Müller and his colleagues have shown that a single atom is sufficient to measure time. Conversely, the frequency of matter can be used to define its mass.
Sakis Koukouvis's insight:
In a paper appearing in the Jan. 11 issue of Science, Müller and his UC Berkeley colleagues describe how to tell time using only the matter wave of a cesium atom. He refers to his method as a Compton clock because it is based on the so-called Compton frequency of a matter wave.

Penn physicists have recently shown that simply changing particle shape can eliminate the ring-shaped stain that is left behind when drops of certain liquids dry. In this video microscopy footage from their experiments, watch as spherical particles get swept to the edges, while oblong particles are distributed consistently.

After 5 years of driking coffee every morning, Now I quite, the reasons? First, Coffee affects my stomach, I dont feel hungry. After taking a glass of coffee, my body is more tress like strong emotion than normal. I always feel hot several hours after drinking strong coffee, I would say, but the good things about coffee is making me more creative. So I dont think every one can drink coffee, I'ts depending upon the organisim of your body. I was addicted to coffee something like I cann't live a day without it. But no it's ok, and I feel more comfortable with other drink like fresh tea.
