In physics there has been a sequence of three theories of motion, each superseding its predecessor: Newtonian dynamics, SR and GR. Insights from GR cast the predecessors in new light. With the new insights the predecessors can be reframed in such a way that the transitions between them become...

This is really sad news. The home of the lancaster bombers are abt to close down. Forever. "Woodford Aerodrome, the home of the Lancaster bomber, is to be closed by BAE Systems, ending 85 years of aerospace history and prompting more than 1,000 job losses at Europe’s largest defence...

1. The present universe is observed to be flat. Was it always flat, before it started its accelerated expansion? 2. Is the Riemann tensor zero for this flat universe? Is its geometry that of special relativity? I'd appreciate if Marcus or Ich or any other science advisor weighed in on...

So I have recently read a couple of pop science books on a common subject that were pretty cool. I wanted to make a thread to talk about them and see if anyone else had any recommendation of more reading on the same topic. The thing the two books had in common was that they were both about...

Based on what I have read about the swine flu, it could easily mutate into something extremely deadly, or into something less harmful. The Spanish flu of 1918 killed about 100,000,000 people globally. It had the same name (H1N1) as the recent swine flu (H1N1). I am terrified that within the next...

I just started reading A BRIEF HISTORY OF TIME and I am having a problem understanding Stephen Hawking explanation of why all bodies fall at the same rate. If I weigh twice as much as someone else and we both jump off a cliff at the same time I would tend to think that I would fall faster...

My first post here, so please humor me. I have found no one in my life who can explain this to me: My question is about the base 10 number system. It arises from the rate at which new NAMES are attributed to numbers as they increase. To illustrate, please consider - 10 x 1 unit = 10. -...

History Channel...Arrrggghhh! The History Channel is playing this documentary called, "Earth's Black Hole." During the course of the documentary they ask whether a black hole under the ocean could be responsible for the bermuda triangle... Does anyone edit these things anymore?

In my World Civilization class, I'm reading "World History in Brief" 6th ed, by Peter N. Stearns. I read chapter after chapter, but I don't feel like I'm absorbing anything. I believe it's because the book is non-interactive; there are no exercises. There are some "key questions" in some...

Assuming the Universe collapses into a giant black hole and the energy as a result leads to a 2nd Big Bang, Wouldn't "history" repeat itself? Assuming condition were the same which I don't see why they wouldn't be and energy content will be identical. But the only problem is this would...

Hi everbody, I am currently learning about the quark model in more detail, how the multipletts are constructed and so on. However, I wonder what particles were really found in that time? I found a list somewhere in the net stating: 1937: \mu 1946: K^0,\bar K^0 1947: \pi^-, \pi^+, K^+...

As everyone know learning history gives us the ideal of the past and it also helps us learn from our mistakes. On the other hand, learning literature teaches us to communicate with others. What if one day your government want to get rid of one of the subject. What would you choose? Would you...

Hey all, Firstly I would like to say that I am fully aware that there is a part of the site related to string theory and other related topics, but I feel as this is such a layman question, it probably belongs here. Correct me if I am wrong. Okay, I am sick and tired of people in my...

I asked my brother "What was the greatest date in world history?" He responded: Well, if I had to pick one, certainly the most important date in recorded history for most of the world would be May 29, 1453, the Fall of Constantinople. Much more than just the conquest of the greatest...

What are some good books on the history of the evolution math. (for example: did the romans use roman numerals to do all their math? because, if that is so, they must have all been freaking brilliant to be able to figure anything out :smile: I always think of Asterix cartoons, when they walk...

In the same way every time we look at the stars we see the past of the universe. Can we see our history placing a extremely powerful telescope pointing towards the Earth an arbitrary number of light years away? I know that would require faster than light travel, but maybe we could shortcut...

With all the different quantum interpretations out there, which is your favourite or "most likely to be true" ? I have a real hard time making up my mind about these things, it all reminds me of different religions trying to prove the unproveable. EVERYONE is disagreeing, new evidence get...
