I wanted to share this updated website. To easily watch YouTube videos, frame by frame, go to http://www.watchframebyframe.com Insert the video link, and you can easily move from frame to frame. This is a major upgrade from www.rowvid.com, by the same people, I think. For example: 1...

His talk was not a history of social networking. He presents the idea of monopoly as what a successful, high-return business should strive for. This is just another way of saying what others have said. Warren Buffett looks for a "moat". More commonly it is called sustainable competitive...

I thought about it and moved this Asperger's post to start a new thread, as it is a great stand-alone forum topic. It will place better in searches, which will help PF. Feel free to delete this original, misplaced post.

To stir the pot more, here is another worthwhile idea from Peter Thiel, discussed in "Zero to One A Discussion with Peter Thiel" > Peter Thiel says many of the entrepreneurs in Silicon Valley seem to be suffering from mild Asperger's. But turn it around. Maybe people without Asperger's are...

He never implied that. He used Einstein's work of an example of how great ideas can generate essentially very little for their creator. He laments it and, philosophically, states that is just how it works. The post is intended to point out a very interesting idea that scientists and engineers...

He does not think it, he sees it. He is a venture capitalist. http://foundersfund.com/team/peter-thiel/ The guy is talking from experience. This is wisdom he is offering to those who can listen.

I need to work now, and will vanish for some time, but first... Zoobyshoe, yes, the mindset is different. Many scientists and engineers presumably want to commercialize their ideas, but they need to study some business ideas, to help align their thinking better. Peter Thiel's comments should be...

Peter Thiel is giving a lecture on Startups. He discusses the difference between X and Y, where X is the value produced by a business and Y is the percentage you capture of X; they are independent variables. Technology startups, often based on innovative, scientific breakthroughs, do not...

Albert Einstein’s patents about 50 patents...no, he did not want to make money from his ideas; he was above that. But that is not the point Peter Thiel is making.

I was listening to a lecture by Peter Thiel. He argued that "scientists never make any money", and are "always deluded into thinking they live in a just universe that will reward them for their work, and this is probably the fundamental delusion that scientists tend to suffer from in our...

Elon Musk says SpaceX finally knows what caused the latest rocket failure http://www.theverge.com/2016/11/5/13533900/elon-musk-spacex-falcon-9-failure-cause-solved Elon Musk Offers Icy Explanation For Spectacular SpaceX Falcon 9 Explosion...

The software used by Philip E. Mason to make his "Detailed analysis of Spacex Rocket Explosion" video was Sony Vegas Pro. I downloaded it. To get a copy of the YouTube video to insert into Vegas Pro, this site was great: http://en.savefrom.net/1-how-to-download-youtube-video/ I placed the ss...

is a well done presentation of the SpaceX Falcon 9 explosion. The creator of this video, Philip E. Mason, does a nice job linking the sounds to the video and explosion. Greg... Mason talks some about the oddity that SpaceX did not have its own cameras recording this. Jonathon, is his idea about...

I posted on the NASA forum and asked what was at points A and B, in the last image I posted. A. Not a lot is there, but that is around the height of the LOX/RP-1 tanks common bulkhead. B. That is the frame for the cradle that supports the top of the vehicle.

Here is another observation from the video, http://rowvid.com/?v=_BgJEXQkjNQ Explosion frame 1 (EF1) produces an X, that we have shown earlier, and is shown here again, as the image on the left. Explosion frame 2 (EF2), shown on the right, has a wider and brighter X, and it appears slightly...

The areas above and below, to the left, have vapor clouds. This area of the rocket appears free of vapor clouds. I am not sure what to make of that. Is the column of light just light, or is it flame?

LOX. Here are some videos of liquid oxygen fires, and they are striking!

Thanks Jim. I am sold on the reflection argument, so trash one hypothesis, and time to make a new one.

Ok. That is definitely a point! In argument, there are no vapor clouds visible in that lower area marked by the oval; you can easily see between the rocket and tower, for example. That is a lot of lamp globe effect on what must be a sparse cloud, but certainly possible given the intensity of...

The explosion is not symmetrical. Using the second frame of the explosion, I have the "x-marks-the-spot" overlapped with a circle drawn to show how far, approximately, the blast had proceeded. But notice that flame is present far below the blast circle, and that flame is in the rocket's...

Here is my hypothesis. What we (think) we know: 1. The explosion appears centered on the connection between the rocket and the pipe. The explosion was external to the rocket. 2,. They were fueling the F9 at the time of the explosion. So... is that pipe the place where the fuel is was being...

Here is where the X is located on the rocket before the explosion (the last frame before explosion). Using the X of light places the point slightly higher than in the image .Scott posted.

Here is an X drawn on the first frame of the explosion to match the X of light produced: ll

SpaceX still does not know the cause. This article just appeared, from Nature World News, dated Sep 13, 2016 04:10 AM EDT http://www.natureworldnews.com/articles/28594/20160913/musk-spacex-rocket-explosion-most-difficult-complex-failure-ever.htm

Jonathon, yes, that probably is a bug, but it is not debris from the explosion. Here is a blinking of the explosion in an attempt to locate where the first blast occurred. I used the last frame, before the fire, and the first frame of the fire. I made a better video: Original: Use replay to...

Jim, that is not a piece flying away. Go to 71.94 and look at the point at the bottom left hand corner, and then click until about 72.54. You will see the point go to the top right corner. I think that is a jet taking off from a nearby airport.

This compilation is nice. The first rocket, at 15.5 seconds, appears to explode from higher up than the Titan, in the previous post (which is included in this video compilation). http://rowvid.com/?v=m6qJh9upqW8 You might notice that these explosions are very different from the SpaceX disaster...

As a side note on rowvid.com, I was puzzled by that domain name, so I looked into it. From http://hackersome.com/p/CalumJEadie/rowvid-version-0 "RowVid was originally created by Calum Eadie, Andrew Ratomski and https://twitter.com/busterlj [Broken] at an Entrepreneur First Hackathon, to help...

This is the 'raw' site: You can't use YouTube to advance by frame. Use this link: http://rowvid.com/?v=_BgJEXQkjNQ (You can use that site for other videos too. ) Or http://anilyzer.com/ With that said, you got the first frame of the explosion, or what I get, at least. But using rowvid.com is...

Musk is asking if anyone else has photos or videos, so conjecture away! They have all the technical info, and they are stuck and need help. The people here might make a difference for them, by seeing things differently. Try it, for real. What can you deduce from the video? What do you see?

As already posted on PF, and you have likely seen in the news, a SpaceX rocket exploded, September 1, 2016. Elon Musk is reaching out for help in finding out how it happened. http://www.csmonitor.com/Science/2016/0911/SpaceX-needs-you-Musk-calls-on-public-government-in-explosion-probe I took...

This was too funny to not share. Numerous agencies are picking up the story, but just in case: Professor's airplane math leads to flight delay An Ivy League professor said his flight was delayed because a fellow passenger thought the math equations he was writing might be a sign he was a...

Thank you andrewkirk. Maybe " 'a' is the geometric mean multiplier of 'b' for the geometric mean." This gives priority to the known unit(s), and, in the example of only two terms, let's the reader assume the geometric mean is the square root of the product. That approach keeps the sentence tighter.

In a geometric mean equation, say 2 x 8 = 16, or a x b = c, what are the words we would use to describe the numbers or terms? Specifically, if you know 'a' and 'c', what do you call 'b'? For example, in a normal multiplication, a x b = c, 'a' is the multiplicand, 'b' is the multiplier, and 'c'...

That video was great, and your research to find it is impressive! Thank you for doing and sharing!

This Comedy Central Colbert Report interview with mathematician Edward Frenkel, as a promo for his book, Love and Math, is quite entertaining, and worth watching if you like math, and maybe more so, if you don't: http://thecolbertreport.cc.com/videos/xj9d66/edward-frenkel

I almost changed the wording, afraid that would be the take. No... I meant to say: I wonder if the velocity of the star (and its imaginary earth) would be great enough for astronomers, living on US-708's 'earth', to notice constellations changing over time, or notice some stars (close ones)...

But your clock on the US-708-earth would tick more slowly than here, so you'd still accumulate the same number of seconds, and your life, as you live it, would not be any longer. But of course, the supernova would have ended it anyways! Ignoring all that, and playing here a bit, I wonder what...

I like that, Drakkith. Here is another image, that is clearly an artifact.

In researching a planned post about M87's globular clusters, I again have been diverted. Being a rank amateur, I was studying how to use Aladin. Looking at some YouTube videos, I found this odd one, "Planet Like Object Found on ALADIN". The object looks bizarre, like the guy drew it in the...

If you place a bowling ball on a trampoline, you deform the 'space'. That is curvature. If you have a large tub of water, and you pull the plug, the water goes down the drain. That is absorption. In 3D space, both follow the inverse square law, with the degree of curvature of space, or the...
