@@saaramb3452 you can prepare anti matter using particle accelerator.. but you need at least a gram of that antimatter to harness the energy for building the Dyson sphere around a star...let us a assuming that you want to build one of those several Dyson spheres around our very own sun... Then you need start recruiting at least half of our current world population as the labor force required for this project. Assuming that you are a very good public relations company and have recruited half of the world population for this horundus task, still you need atleast a gram of anti matter to use it as start off to provide you energy for this start up job, but our current particle accelerators at CERN can produce about 100,000 anti protons per day and each of these last an average of 10 seconds.. So a gram means ahh... Let's assume it to be hydrogen's anti protons for calculation purposes 1 mole of anti-Hydrogen is 2 grams that (because hydrogen exists as H2) which means 1 moles of anti-Hydrogen contains (6.023*10^23) anti hydrogens so 1 gram is (3.0115 *10^23) which requires you to prepare a particle accelerator that is as efficient as that it need to create 3.0115 *10^23 anti-protons( I m using the word proton instead of hydrogen because it doesn't matter hydrogen can be called a proton as it has has only one proton and we count the proton and neutron for mass number) so the particle accelerator should work at an efficient 3.0115 *10^17 times the one currently being available. So in plain word's if we have the materials we would have done that long ago, unfortunately we don't have the materials we require. A gram of anti matter costs around 62 trillion dollars which means you need to sell your country for that!

In 1D it would be 2 points "randomly" selected out of 2 points on a line, probability of 1/2 that it is the different point and the connecting line goes through the center. For 4D and above I think it's quite helpful to move away from the visual intuition and describe it formally, but it is still the visual intuition that was the key to the solution.
@BurgoYT7 ай бұрын
Yes good point and the 1D case would be very easy too, the probability that two random points on a line when connected contain the centre. Doesn’t matter which side of the centre the first point is on, the 2nd point just needs to be on the other, which is of course a 1/2 chance as you said!

The thing is: this doesn't actually help you solve those problems. They are designed in such a way that you have to have the right understanding and intuition to solve them. Anybody can solve them if they know the correct method - but nearly nobody does and there are so many problems and variations that can be given that no person can ever hope to come even close to remembering them all. hat is needed is the ability to come up with the solution on your own - and that is hard.

I am taking a Putnam exam prep seminar and this problem was on our homework for this week. I solved it a few days ago. My solution wasn't quite as elegant as the one in this video; I used a triple integral to find the average area of a spherical triangle, making use of a symmetry in the "area of a spherical triangle" function to avoid having to actually find a formula for it. In hindsight, I could have made use of even more symmetries (specifically, the fact that there are always seven other triangles that add up to the whole sphere), which is more or less what you did. My solution: When we choose three random points on a sphere, we get three random variables that we can use to calculate the triangle's area: θ₁ = angle along arc from point A to point B θ₂ = angle along arc from point A to point C ϕ = angle at point A between the two arcs All three variables are in the range [0, π]. They are independent with probability densities sin(θ₁)/2, sin(θ₂)/2, and 1/π. Let Area(θ₁, θ₂, ϕ) denote the area of a spherical triangle, where the area of the whole sphere is taken to be 1. Note that Area(θ₁, θ₂, ϕ) + Area(π - θ₁, π - θ₂, ϕ) = ϕ/2π, since together these two triangles fill up the region between two meridians ϕ radians apart. The average area of a spherical triangle is ∫ ∫ ∫ (sin(θ₁)/2) (sin(θ₂)/2) (1/π) Area(θ₁, θ₂, ϕ) dθ₁ dθ₂ dϕ = (1/4π) ∫ ∫ ∫ sin(θ₁) sin(θ₂) Area(θ₁, θ₂, ϕ) dθ₁ dθ₂ dϕ = (1/8π) ∫ ∫ ∫ (sin(θ₁) sin(θ₂) Area(θ₁, θ₂, ϕ) + sin(π - θ₁) sin(π - θ₂) Area(π - θ₁, π - θ₂, ϕ)) dθ₁ dθ₂ dϕ = (1/8π) ∫ ∫ ∫ sin(θ₁) sin(θ₂) (Area(θ₁, θ₂, ϕ) + Area(π - θ₁, π - θ₂, ϕ)) dθ₁ dθ₂ dϕ = (1/16π²) ∫ ∫ ∫ sin(θ₁) sin(θ₂) ϕ dθ₁ dθ₂ dϕ = (1/16π²) ∫ sin(θ₁) dθ₁ ∫ sin(θ₂) dθ₂ ∫ ϕ dϕ = (1/16π²) * 2 * 2 * (π²/2) = 1/8.

In this case, *tetrahedron is a prism with 4 triangular faces, 6 straight edges, and 4 vertices (aka corners).* Hope this helps you

When I was in college we had a “project” that was due in a week. We were tasked to write a simple program that enabled the user to enter three, 3-coordinate points in space and have the output give you the area of the triangle. I solved it in one day and my answer was given on a single side of a single sheet of paper. The following week, all my classmates turned in these huge packets with dozens of pages in them. The following Monday the professor gave back all the graded papers except for mine. He held up my single sheet answer and told the whole class that their work was shit and that this is how your answer should look. I felt like a million bucks.

@xxNewEraxx it requires 3 dimensional calculus, so unless you’ve taken advanced calculus of the type you only see in Engjneering or Mathematics majors in college, it isn’t that simple. I’m fact, everyone else in the course started their project with the same failed premise as you and that’s why it took them piles of useless paper and theory to attempt to solve it. With 3D Calculus it has a simple and elegant solution.

I did the problem with a square and it made it way simpler to do it with the circle! It’s really interesting because framing the question in a certain way makes it so that the shape of the object is almost arbitrary! I inscribed the circle in a square. I then divided it into 4 parts by the diagonals. Take an edge. That edge is 2 of the 3 points of your triangle. Now move the last point and note the area under which the middle is covered. That area should be only one of the 4 parts of the square that you cut using the diagonals. Using the same diagonals, you get 4 of these situations because there are 4 edges and each of them gives you 1/4. If you take a fresh square now and make 2 cuts that serve the same purpose as the diagonals in the other case, you’ll find that you have another set of 4 configurations that give you an average area of 1/4 because each set of 2 is mirrored. Since the circle is inscribed and we used areas we can use the same cuts for the circle and it still holds. If you do the same thing with a cube and make 4 cuts. You can do the same thing but you get 1/8. This shit is so cool

in 1D, the 'circle' is a line segment. Imagining point A is fixed, point B could be closer to the center or closer to point A. if B is closer to point A, the center is not contained. if its closer to the center, it is contained. since B could be on either side of the center, and the center splits the line segment into 2 equal pieces, the odds are 1 in 2. This aligns with the pattern found in the 2D and 3D cases, where the probability is 1/2^D where D is the dimension.

I figured it out before he introduced the 2 dimension example. All points of the sphere are equal and so the average of random distribution cuts the sphere in half 3 times over, the same likelihood as 3 heads in a row. Doesn't work with 5 points unless working in 4 dimensions, dividing each vector of the dimensions, which is 1/16th or 4 heads in a row. I don't have a high school education.

Heres a problem for you Taran, say if you have 104 keys on a keyboard, how many macros could you bind if you could press 10 buttons at once to make a shortcut.
@TaranVH7 жыл бұрын
Answer: Nice try. Even if you could remember them all, it's impossible to accurately press down 10 arbitrary keys simultaneously. Even two keys simultaneously is a bad idea, unless one of them is a modifier key. If it's macros you're after, a secondary keyboard is the way to go. In that case, more than one modifier key at a time is usually inefficient. Also, WIN and ALT are dangerous under most circumstances. Therefore, only CTRL and SHIFT remain. Therefore, the most macros you can safely get out of a 104-key keyboard is: 104 - 8 modifier keys x 3 (CTRL, SHIFT, and unmodified) = 288 macros. 384 If you include the double-tapping of a single key. (Tapdancing) Of course, it's easier just to add another keyboard rather than use modifiers in this way, which is, of course, why I have 3 keyboards and counting. Yeah, totally took the bait on that one.

My friend told me about this exact problem about a circle and three random points. My argument is that if you take a triangle ABC inscribed in that circle such that it contains the center, consider points D,E,F that are diametrically opposite to A,B and C respectively. Now, for every such ∆ABC, there exist three triangles named BDC, AEC and AFB and they are uniquely attached to this triangle ABC there is no way you can get the same three triangles with different such center containing triangle Hence there are three no center containing triangles for every center containing triangle so probability should be 1/4

No, but if they've given us the uniform density and radius of the sun, it should be a piece of cake, even that's not necessary, if we're given the gravitational force between earth and sun, with the distance between then and earth's mass, we can easily find the sun's mass

I'm kicking myself. I tried thinking about this on my own for a bit, but I couldn't get my head around it even in two dimensions. So I simplified this problem down to ONE dimension and then understood it perfectly: given an interval and two random numbers within the interval, the center of the interval is only between the two random numbers if they're on opposite sides of the interval, which has a probability of 1/2. Then I couldn't figure out how to generalize to multiple dimensions, got lost, tried to think about properties of triangles, and thought, "Now I'm going to watch the rest of the video and realize I had a really hard problem by the neck and couldn't do the final step" - and it was true! Three points on a circle contain the center if two of the points are on the opposite side of the circle from the third! Four points on a sphere contain the center if three of them are on the opposite side of the sphere from the fourth!

I don't know how it's possible, but I was able to find the solution to the 2D problem after just few minutes, when I first saw it I thought "I def need to put this in 2D". I didn't solve the whole problem, 'cause I got bored and just wanted to see the solution, plus I'm in the second year of highschool and we didn't have probabilities yet. Still I'm very happy I figured out the first easier half, since in school I'm average at math.

I've managed to solve it on my own in a very different method. Just at the beginning i want to adress that it's not a great method because it doesn't prove the concept but manages to give a "proposition" of the answer. My method involved solving this problem in different dimensions. Instead of solving the 3D sphere with 4 points, I solved the 2D circle with 3 points, 1D line with 2 points, and 0D point with one point. I assumed that the number of points would be the case because 0D point has max 1 point and line has 2. After that, for a point it was 100% obviously and in a line 50%. The only hard part of this method for me was solving the 2D version because im not very good with probabilities but after a while i realised that we just choose a random number between 0-1, and then the probability is this number squared. I then proceeded to square the average of 0-1, one half, so the probability came as a quarter, 0,25. The only thing left for me to do was notice the pattern, 0D - 1/1, 1D - 1/2, 2D- 1/4, 3D -1/8 (1 over 2 to the power of the number of dimensions for this problem)
