I found this great demonstration video of quantum levitation and just had to share it. http://www.youtube.com/watch?feature=player_embedded&v=Ws6AAhTw7RA

I am very interested in video game development but also other things like, computer programming, network security and robotics. I mean you hear all the time, that the United States needs more engineers to compete with other countries. I'd like to try to be a part of the country's bright future...

Hi there, I am using a PC to TV converter fairly unconventionally. I'm connecting a VGA output to a PC to TV converter. This converter outputs a composite video which I then connect to a USB Video Capture Device, which feeds into my computer . The resolution of the image I want to capture...

My girlfriend is christian and completely denies the existence of evolution. She's always reading or watching anti-evolution books and movies, and doesn't seem to actually understand what the theory of evolution is about or claims. I, on the other hand, do accept evolution. She wants me to...

This makes me wish we didn't have so much light pollution here. This is a nice timelapse video of the milkyway. http://news.yahoo.com/blogs/technology-blog/jaw-droppingly-gorgeous-video-captures-milky-way-earth-234619211.html

Hi, Can anybody recommend me a good video lecture series on introductory digital/logic design? I want to watch these while I'm on break from my studies. Thanks

Anyone have any suggestions for video lectures that go beyond the standard overview-for-the-layman or slightly-lower-level introductory courses? A post somewhere on here pointed me to Susskind's "Theoretical Physics: the Bare Minimum" on "iTunes U", which is sort of the prototype for what I'm...

Why does glass get elastic when immersed in HF; like this video? Hi, I was surfing YouTube and came across a very interesting video... Check it out yourself; http://youtu.be/gzUDjHDj0fQ" Why did the glass become elastic? I was thinking it might be due to destruction of some bonds...

I made a relativity video for my father as he's been asking a long time. His question is basically how can light always travel at the same speed no matter where you are. So to answer it and since he's far away I made this video If someone could check it and let me know if it's wrong or...

I ran this experiment to find out what a gun would look like while shooting under water. Turns out to be quite interesting. The muzzle blast is NOT spherical as I first assumed. Regards, Mrpennywhistle

If some pre-med students want to study Physics by watching university-level video lectures on Physics-1 (Classical Mechanics) and Physics-2 (Electricity & Magnetism), what site would you suggest to them? (They already know of Walter Lewin, Ramamurti Shankar and Khan Academy). Can you suggest any...

I want to know why someone hasn't built a 'rover' of some sort that could easily navigate the lunar surface while recording HD video. I don't think funding would be an issue since you could easily strike a deal with a large company pertaining to product placement i.e. a coca-cola bottle in the...

Hello everyone. I am just exiting high school and will be going for an aerospace engineering degree this fall but in the mean time I wish to study physics. I am terrible at learning by reading, I cannot stay focused and drift off very easily, reading it but not soaking any of it in after more...

Hi all, Love the forum, just signed up but have been reading for a while. I'm not an EE and I am working on some image processing, so I need some hardware help. What I want to do is to have ~20 USB webcams, of which any 4 are selectable to feed into MATLAB. I have the software side running, but...

Can anybody help me with finding video tutorials for Pro Engineer Wildfire 4

Paul Steinhardt (Princeton cosmology expert) just gave a cogent talk at Perimeter Institute criticizing inflation. http://pirsa.org/11070029/ The talk clearly lays out the problems with expansion cosmology that inflation was invented to address and again very clearly explains the ways it is...

This isn't a homework problem, but I'm going to make it sound like one because I think that's the best way to explain it. An hour-long video on the computer loads 1/3rd of a second of footage every second. The video can be played while it is loading. a)What is the minimum amount you have to...

I am writing a video card driver. One timing parameter I have to pass is H/V Blanking interval start/end. I have all the standard timing information but can't figure out how to get the blanking start / end pixels.Here are my current calculations, I don't think their right however (you can...

Before you watch the video, give your answer here... and why you think it's correct.

Downloading a streaming video -- possible? Wasn't sure where to post this. So there's a streaming video online of Israel's main news channel segment where my hand makes a cameo appearance (lol)-- don't ask why, but I want to download it as a video :smile: The clip...

The US Supreme Court ruled that http://www.supremecourt.gov/opinions/10pdf/08-1448.pdf. A few things were notable about this decision. For one thing, Scalia and Thomas were on opposite sides of the issue (they almost never disagree on decisions). Secondly, Alito should be commended on his...

Erik Verlinde gave this great talk at Perimeter on Wednesday last week, which is online as video. It was at a recent Holo Cosmo workshop they had there http://pirsa.org/C11010 It is a very exciting talk. He is actively grasping for what many people dream about: a concrete way to think of...

Wanted: video by Wilczek on "The Grid" Does anyone know of a video lecture on the WWW by Prof Wilczek describing his theory of the Grid? (Suitable for someone with a basic science knowledge.) Thanks.

I understand that I don't "get" the whole HD video thing but regardless, what the HELL is up with video files with 60 fps? One needs an expensive computer to adequately display such a film and for what? Is there really some dumb *** who has tricked himself into thinking he can even SEE the...

Interesting http://www.ted.com/talks/ed_boyden.html?utm_source=newsletter_weekly_2011-05-17&utm_campaign=newsletter_weekly&utm_medium=email", I thought I would pass it on. Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or...

Would someone who has been around longer than me know of any books or resources to explain how analog video works. Most stuff I have found seems to be more software based or are geared towards photography rather than laboratory work. I have been looking in the literature for my work and some...

Hello everyone, I have a basic (I think) question about how a consumer video camera is programmed to do what it does. The camera I have in mind is the Flip (may it rest in peace). Ok, so I'm aware of most of the parts that go into a video camera, such as the shell, controls, lens, sensor...

Hey guys, I'm so glad I found this forum as I been going nuts trying to get a good flash video recorder for my web site. I have searched all around the web, but didn't found what I'm looking for ... Does anyone know of any good flash tool that allows users to record short video messages and...

I am working on a space balloon project and I wanted to send video, or pictures, back to Earth via walki talki. I wanted to know if this would work; I connect a composite video cable from a camera to the wires of one of the walki talki's microphone wires. Then on the other end take the wires...

http://pirsa.org/11040063/ Big Perimeter audience, appreciative interest, long question period after. He undercuts his critics (who said the concentric circles could have appeared by chance) by criticising their methods and makes at least one valid point. I would say that the critics still...
