Hi guys, I have recently come across a video on YouTube which gives you a brief intro to Quantum Mechanics/Physics. Can someone tell me if this video is accurate? Could someone suggest some introductory reading or resources for learning QM? Is it even accessible to a 15 year old? Should I just...

I enjoyed this video about tensors very much. I would recommend it to anyone seeking to understand the concept in general and general relativity specifically. https://vimeo.com/32413024 You can fast forward through the repetitive parts and try to place yourself in the role of beginner as you...

Hello Physics Forums: I wanted to share a new science-education video series called 'Think About'. We just completed the first eight mini-episodes. 'Think About' airs on American Forces Network (AFN) and the audience is pretty special: kids that are overseas with their military parents. The...

Hey Guys I am making a series of physics tutorials.. with an aim to solve problems and understand concepts without making using of any formulae by making use of animations and some real life examples I started with conceps of relative velocity.. Please tell me if its useful.. I am sorry...

Hi, Can anybody recommend me a good video lecture series on Introduction to digital logic design? I want to watch these videos before going to class.

if possible could you tag some good video lectures may be feymann or any other good source..thanks...!

CRT televisions use electron guns to fire electrons at color phosphors on the screen which emit the light of varying frequencies to produce an image. They can scan row by row or column by column depending on the standard of the broadcasting signal though modern models have circuitry that can...

Greetings, I am currently building a new system and I am trying to get the most bang for my buck. my concern is over the video card currently. I have two in mind but I don’t want to pay for something that I won't get the full performance out of. Both cards are Asus, the first is the GeForce GT...

Hi, This will be the last time I bother you with this for a little while. I have produced a rather amateur video (4min) of what I think handwriting recognition for maths should look like. For the time being, I have named it MathPen. http://users.ecs.soton.ac.uk/cmml100/VIDEO0012.mp4 What I...

Homework Statement We are not allowed to use any videos from youtube. They have to be a realiable source. We are having difficulty copying the embeded link to the power point presentation. Homework Equations The Attempt at a Solution First, we right click on the video to copy it...

http://www.icarusengineering.com/Dynamic-Soaring-and-SE.htm I am trying to validate dynamic soaring versus normal thermal soaring, but both are using thermals as the power source. Dynamic soaring would mean using 2 types of air masses. One in the thermal and the second one is the inflow to...

My friend and I had an idea to put camera on the weather balloon and we wanted to have like a live picture from camera. But because we don't know so much about electronics we don't know how to do it. Fe figured out that we can do it via radio waves, maybe there is some more efficient way. That...

Does a chess program game knows every move that you can make? Does that mean that every possible outcome exists in the chess game and it just creates a path everytime you play by saving that path? Does this apply to more complex games with open worlds? So would it be correct to say the second...

I thought it was pretty straightforward until 4:26, until they started making some questionable claims. I'm no expert so I thought I'd ask here. http://www.youtube.com/watch?v=0ca4miMMaCE

hi gang, got a friend who lifes relatively close to a 1407kHz (multi kW) AM broadcast transmitter he has a ~ 50metre run of 75 Ohm coax between a security camera and the recording/viewing equip. The 1407 kHz is getting into the system and causing the usual herringbone pattern on the displayed...

I've been interested in this function Youtube offers on videos ever since I first used it a few months ago. It's amazing. Some videos are just way too long. The speakers will have something very informative to say, but they'll just ramble and/or speak very slowly. For some reason, Youtube only...

Hi, What is the best solid state physics video course available online. So far the best one i have found is this one .. but it is just introduction to Solid State Physics

I am working on one project. In which I have CCD image sensor (Sony's ICX254AL ) and its output is connected to Analog Front End (TI's VSP2562). The output of Analog Front End (AFE) is 12 Bit Digital data at the rate of 9 MHz. I am thinking to use NI's PCIe 6535 as a data acquisition device to...

Hey people, 1. The problem statement, I'm doing a Uni Art assignment, and I'm going to be projecting a video onto a canvas (which I don't know the exact dimensions of yet). Video file dimensions are stated as 1080 x 980 and so forth, whereas the real life canvas will be something like 50...

Today, my teacher showed us a video in class (AP physics B) as part of our quantum physics unit. I'm really skeptical about the video, and I wanted to seek the opinion of people who are actually knowledgeable in this field. Is there anything wrong with the information provided...

The video, http://www.youtube.com/watch?v=XDCk0DaNwiQ&feature=results_video&playnext=1&list=PL28AFB6F1D7079B62 Observation of our chickens, when a chicken walks the head is kept motionless and then moves quickly to a new position, repeating over and over again as the chicken moves forward...

http://www.youtube.com/watch?v=AuYFcjBmMJ0&feature=relmfu at time 34:35. He says it depends on how fast the air is flowing by? So does that mean the velocity of sound in the equation f=nv/2L change? How are the different sounds produced?

http://pirsa.org/12040059 Fine presentation today, room packed, good questions from audience (esp. from Turok but also from others.) Rovelli will spend several weeks at Perimeter during which time he also makes a side trip to Princeton Institute for Advanced Study to give a slightly different...

I recently came across an interesting video. What do you think it might be? http://www.youtube.com/watch?v=Ypqfq0SYrAQ&feature=player_embedded

I just can't watch Prof. Gilbert Strang on MIT. His stuttering and slow pace is just too much for me. Is there another series on the typical first course in Linear Algebra available in video form that I can casually watch as a companion to my textbook and lecture?

OK shot in the dark here but here is my question prefaced with a small back-story. Im a undergrad in mechanical engineering program. I am currently having a bit of trouble in Dynamics class. A lot of people who are much smarter than me say its nothing more than applied physics. Like some guys...

I confess, I stole this from garrett's twitter page, enjoy... Quoting the pilot's caption at the end: "and suddenly you are free, a really intense feeling of freedom. The true feeling of flying, a magical moment. The best feeling I have ever felt in my life" Rhody... :biggrin: :devil:

All: This is a weird question. I'm trying to find a video or TV program, I'm hoping someone else saw this and can tell me what it was. There was a mouse or frog in a box or cylinder. They were experimenting with EM fields, very high energy and they were shaping the fields. I think this...

I give you... World Builder, by BranitVFX, sit back and enjoy... amazing editing, two years worth. Rhody...

Hey! I'm a filmmaker and just thought I'd post my video I made that is inspired by physics and the beauty of the universe. http://vimeo.com/36267608

What do you think?

Hi folks, its been a while since I've visited. I had an idea a few years ago I never pursued and I thought I'd run it past this group simply because not only is it beyond my education to develop but its combining both optical physics and some techniques used in cosmology. OK so here goes I...

I think the video is clear enough: http://www.youtube.com/watch?feature=player_embedded&v=qHrBhgwq__Q. Looks like a nice game.

Are there any chess players, statisticians, or smart people who are familiar with the ELO ranking system? This concerns a game with at least over 100,000 players, so its not an obscure concern. Basically, I play an online video game that tries to apply an ELO ranking system to rank...

I found it very entertaining last semester watching Walter Lewin lecture on Physics I topics whilst taking the course and reading my textbook. I'd sad to see that he doesn't have a video set for physics II topics! (waves, electrostatics, et al.) Does anyone know of a similar style video...

Are there any theories with which the mass effect fields of Mass Effect and the slipstream space of Halo draw inspiration from? Is there any scientific basis for either, or is it complete fantasy?

Here's the video. http://www.youtube.com/watch?v=w_iP3ZrIb88 What are those streaks running across the video? I don't mean the specks (which they say is caused by radiation damage to the video) , but the streaks that seem to have a direction. Sometimes they come towards the camera...

Replacing Monitors - "Cannot display video mode" I'm switching out my old CRT Compaq FS7600 monitor (for specifications: see the link below) for a dell flat screen monitor. Unfortunately, this monitor says nothing about the model type, and I don't have the box as I got this from a friend. The...

In the below video from approx. 12:00 onwards while explaining the proof for Quotient Rule, Mr. Miller says that while delta x approaches zero, delta v approaches zero. Can someone explain me why is that? Thanks a lot!

I am looking for an answer based on Logic and not necessarily a technical one. Suppose, if I have a video clip of me doing something (let's call it event 2: E2) and would like to convincingly prove to others that it happened after a certain date - say, 2011-01-01. One rather simplistic idea...

https://www.youtube.com/watch?v=6IQ15ymhR2M This clip from the history channel as is titled, attempts to address the likelihood of David killing Goliath with a sling. As you can see in the video, the pro Slinger when testing the force on a load cell, got a reading of 3.62 kN or 3620 N...

New Video on "One trillion frames per second camera" Here is the video: Mods, please delete if there is already a thread for this. I think this is a great achievement by the researchers. It's an interesting topic, so maybe people can use it to ask questions on how/why it works, and...

Video Monitor Jack repair I have a Fahrenheit 7” LCD Wide Color Vision monitor that has a broken jack. From the monitor is only this female connector: Then there is a cable that goes from 8 pins to 24 pins (I count 12 on each half?): Next after that cable is the box, where the...
