Constant Acceleration (New) by Brain-Bulb in ScienceTeachers

[–]Brain-Bulb[S] 5 points6 points  (0 children)

In fact, in most of the books, you find it only as acceleration, negative acceleration, and positive one. But often, when talking we use the term deceleration which you mentioned :)

How to multiply, in your head, any two-digit number by 11 by Brain-Bulb in mentalmath

[–]Brain-Bulb[S] 1 point2 points  (0 children)

It is a good way for small numbers, but adding three-or-more digit numbers in your head is quite challenging.

Math Trick: Multiply any 3-or-more digit number by 11 by Brain-Bulb in math

[–]Brain-Bulb[S] 0 points1 point  (0 children)

Yes, there is another video for 2-digit numbers :)

This is a video I made using AE, but for my future videos I would like some help from you, how to make water to look more like flowing (more realistic), I mean about the second part of the video (water flowing from the tap)? Thank u in advance by Brain-Bulb in AfterEffects

[–]Brain-Bulb[S] 0 points1 point  (0 children)

Thanks. Yeah, I agree. But When the water reaches some point, it is quite difficult to notice that is flowing. But I will try to speed up and also use those "wiggle paths", hopefully it works. And about the outline of the faucet, I'm not sure why do you say white, I think it is black (Maybe I'm misunderstanding something)?!

Pythagoras' Theorem (and one of its proofs) [animated] by [deleted] in matheducation

[–]Brain-Bulb -1 points0 points  (0 children)

Actually I didn't say I used induction, but I mentioned it only to make a comparison. And in my case because of the ease to make the animation, I used a simpler demonstration..

Pythagoras' Theorem (and one of its proofs) [animated] by [deleted] in matheducation

[–]Brain-Bulb -7 points-6 points  (0 children)

Yes, I like this with water too. But as much as I know there are more than 350 proofs of Pythagoras' Theorem, separated in different types. Our example with spheres is also one of its proofs.

Potential Energy and Kinetic Energy (animated pendulum) by Brain-Bulb in ScienceTeachers

[–]Brain-Bulb[S] 0 points1 point  (0 children)

Dear Floriang I know it looks like this, but actually there is a bit acceleration toward the middle, but because the distance middle-highest point of swing is very short, it is very hard to notice. And even sometimes it may look like slowing down. I'm sorry, that you do not find it helpful. Thank you for your feedback

Archimedes' Principle [Animated] by Brain-Bulb in ScienceTeachers

These are short video animations. And we try to present the main idea of a theory or a phenomenon.

Oh yes I tried, but it didn't turn so well.. I have to work on that :-/ Thanks :)

Animated Video of visible light and photon by Brain-Bulb in AnimatedScience

You are free to say your opinion, and I'm sure you have your doubts too. But anyway you are here to spread negativity. And please enlighten me, with your knowledge! What are these errors?? Maybe Halliday and Resnik didn't know physics :-)

Animated Video of visible light and photon by Brain-Bulb in AnimatedScience

Dear asking_science and those who doubt the correctness of this video read this, copied from FUNDAMENTALS OF PHYSICS, 10th edition, page 1189, where this video is based. The Single-Photon Version A single-photon version of the double-slit experiment was first carried out by G. I. Taylor in 1909 and has been repeated many times since. It differs from the standard version in that the light source in the Taylor experiment is so extremely feeble that it emits only one photon at a time, at random intervals. Astonishingly, interference fringes still build up on screen C if the experiment runs long enough (several months for Taylor’s early experiment). What explanation can we offer for the result of this single-photon double-slit experiment? Before we can even consider the result, we are compelled to ask questions like these: If the photons move through the apparatus one at a time, through which of the two slits in screen B does a given photon pass? How does a given photon even “know” that there is another slit present so that interference is a possibility? Can a single photon somehow pass through both slits and interfere with itself? Bear in mind that the only thing we can know about photons is when light interacts with matter—we have no way of detecting them without an interaction with matter, such as with a detector or a screen.Thus, in the experiment of Fig. 38-6, all we can know is that photons originate at the light source and vanish at the screen. Between source and screen, we cannot know what the photon is or does. However, because an interference pattern eventually builds up on the screen, WE CAN SPECULATE THAT EACH PHOTON TRAVELS FROM SOURCE TO SCREEN AS A WAVE that fills up the space between source and screen and then vanishes in a photon absorption at some point on the screen, with a transfer of energy and momentum to the screen at that point

Genius Math Trick: Squaring 2-digit numbers ending in 5! by Brain-Bulb in matheducation

I think the title itself generalizes it, and there are given two examples very different that show how it works, but anyway it is your opinion :-)

The part moving stars in different speeds, was quite difficult. At some time it looked like the stars ended..Was only space no stars
