They do have all of the information available online though. http://noosphere.princeton.edu/ For example on the case of nine eleven you can take a look at: "the primary results" --> 80. Terrorist Disaster, Sept 11, 20010911 Also note that because their information is publicaly...

I am wondering... It wouldn't be hard to do this kind of experiment yourself, right? All you need is a random bit generator and a constantly running(not crashing) computer. Eventually some major event will happen again and we could see the outcomes ourselves. Anyone volunteering :smile: ...

That is when you assume that their more primitive signals didn't reached us already long ago. But I'm not so sure about the fact that we would be able to detect their radio signals... Thus you are claiming that on Mars we would detect radio signals coming from earth? The power of that...

You could ask the same question about ourselves. Why are we sending such expensive equipment to Mars to see if there is any basic form of life? You are right that they wouldn't be interested in our technology, but there are a lot of other things, not only about us but also our environment, that...

You might already have heard of the book "Gods of the new millennium" from Alan F. Alford. If you don't know what it's about, this is what the back of the book says: The appearance of Homo Sapiens 200,000 years ago defies the principle of evolutionary theory, whilst the Biblical account of...

If you hand the solved problems out, at least the students don't wast their time by writing down the solution. Instead they could try to understand it already. Because believe me, when you are writing things down you don't always have the time to understand things too. But this doesn't apply to...

Well a capacitor is actually two charged conductors very close to each other, so there's a voltage difference between them, right? And a coaxial Cable has an inner and an outer conductor, so those two conductors are responsible for the capacitance. That means the capacitance has to be parallel...

Anyone? Or is my question not clear enough?

Attachment And here's the attachment :).

First take a look at the attachment (See reply below). We have to take the oscilloscope's impedance and the coaxial cable's impedance into account. And then we have to calculate the cutoff frequency of this. Given: Oscilloscope: R=1M Ohm // C=25pF Coaxial Cable: R=75 Ohm and C=68pF/m...

What did you study specificly then if I may ask? I'm an engineerstudent at the moment and I was very interested in the physics classes. That's why I'm thinking about studying physics too after I completed my engineer studies. But then again that's another five years added to my engineer...

For those students who live in Europe, has anyone of you participated in the Erasmus exchangeproject? If so, what country have you been too (and where do you come from of course)? How long have you been there? Was it an experience you would recommend? And what did you think of the level of...

I'm an engineerstudent at the moment and I feel like I was really interested in the course modern physics. I'm really fascinated with the theory of relativity, quantummechanics, corephysics (or how do you name it in english?),... But that course was only qualitative and covered only the basics...

I've had one course of chemistry every of the first 3 semesters. It was anorganic, organic and some industrial processes. I'm doing ICT engineering (electronics, computer science) and also having big trouble with chemistry, it really is a pain in the ass (still have to take my last exam of...

So no one knows why water sublimates at this pressure?
