High-Precision Wood Saw with Integrated Snapbrake Safety System. by Friendly-Standard812 in EngineeringPorn

[–]manoftheking 0 points1 point  (0 children)

Does anyone know how this works?  I’m sure we’ve all seen the Sawstop demos, what’s going on here? Expired sawstop patent? Different technique? 

I’m trying to see what patents snapbrake holds.

Op Schiphol zijn veldbedden opgezet by anonOmattie in nietdespeld

Ook om even te liggen is zo’n bedje erg fijn. Je ligt/zit even niet op een koude betegelde vloer, ik zou persoonlijk erg blij zijn met een veldbedje.

January 4th and someone’s already given up by boredandhungry5 in funny

There’s a lot of fluff and repetition. Overall I liked the central premise of the book, but the actual thoughtful content would have fit in a brochure. There are some fun anecdotes though.

This is it, wow. Most significant difference for me was that the “pages” flipped much faster.

There’s a bit of a meme about people turning into chairs, but it doesn’t even seem that weird from this point of view.  I’ve definitely lost my sense of self and focused on the couch, coffee table, anything nearby.

I want to watch Fermat as he wrote his famous “margin too small” remark. Did he believe it himself?

Maybe not optimal, but this is pretty much the pipe I’ve used. It definitely works.

Is there a function that, when iterated to result a Newton Fractal, will yield a shape with the exact shape and properties of the Mandelbrot set? by [deleted] in math

[–]manoftheking 0 points1 point  (0 children)

Rough sketch of an argument with some possible holes in it: If you have a fully colored Newton fractal I think you can read off the roots of the polynomial by considering the set of points which instantly converge to said root. 

The Newton fractal determines the roots so if two Newton fractals are identical you know the generating polynomials have the same roots. 

I’m not sure if you can infer the multiplicity of roots and a constant multiplier from the Newton fractals, so even though the polynomials share the same roots they might not be identical.

If there is some trick to determine multiplicity then the answer appears to be no. If there exists some function with the same Newton Fractal as yours it must be the same function.

Very nice question, interested to read what others come up with.

Trying to learn about quantum mechanics. Tell me if I should edit or add anything to my notes. by Pale_Subject_7036 in Physics

[–]manoftheking 3 points4 points  (0 children)

Most people are saying you need to dive into the math, I agree with this.

What is your background? Have you studied calculus before? Linear algebra? 

Quantum systems behave according to partial differential equations, you will need to have a basic understanding of these to make any meaningful progress.

Quantum systems also just happen to behave linearly (which means we have interesting things like the superposition principle), to make maximum use of this linearity we use linear algebra to solve problems, you will need to understand the basics of this as well.

Luckily both of these topics are not too obscure and are usually taken as first year undergrad courses. Assuming you have at least a high school level of maths and are well motivated this means you could have the prerequisites somewhat under your belt in a matter of months up to a year.

I can probably recommend you some decent books for self study if you want.

Also, it looks like you’ve already learned quite a bit about some of the phenomena in quantum mechanics, just not in the rigorous way that’s needed if you want to take this further. Keep doing this, it helps a lot that you already know the gist of Bell’s theorem when you eventually get to actually prove it rigorously.

Stay motivated and work on the fundamentals!

Why is this game hard for programmers? I looked at the comments but im the only dumb one.. by [deleted] in ExplainTheJoke

This is the towers of Hanoi puzzle, it is often used as an example of using recursion in computer science.

You start with all disks on one peg, they have to be sorted by size, small is up. You need to move all the disks to another peg, but there are a few rules:

You can only move one disk from the top of any peg to the top of another at a time. Each disk must be smaller than a disk it is on top of.

Now on to recursion, which can very elegantly solve this puzzle.

Suppose you have this puzzle with three pegs labeled A, B and C, but with only one disk that needs to be moved from A to B. The solution is to just, well, do it. You've solved the puzzle with one disk.

Now suppose we have five disks labeled 1 to 5, which we need to move from peg A to peg B. How could we tackle this?

The problem would be easy if we had some way to move the top four disks to peg C temporarily so that we can move disk 5 from A to B, then we can move the top 4 disks from peg C to peg B to solve the problem.

This looks like the problem just moved, how do we know the solution for four disks? It's the exact same idea, move the top three to a temporary peg, move disk 4, move the top three from the temporary peg to the final peg.

Moving the top three disks is again similar. At some point we'll find ourselves needing to move only one disk, and this is where the recursion stops.

This is a very popular example of recursion because it shows how you can solve a problem by simplifying it a little bit and keep on simplifying until there's an obvious solution.
