What are some good podcasts that are math related? Preferably statistics or economic related.

I used to listen to freakonomics but it got kind of stale.

It's funny.

OfficialFlatEarthAndGlobeDiscussion (Facebook Group) is the most terrible collection of pseudo-scientific nonsense imaginable. Has anyone encountered flat earthers and managed to make them see reason?

I don't think it 's actually possible to make them see reason.
If you actually bring up any legitimate points against their ideas, not even arguing for the globe model but just problems with their understanding of how things like light work, they will invariably end the conversation.
They're so close minded that they latch onto things instead of checking for logical explanations, like a video capturing Venus near the Sun during the eclipse being called the projector for the Sun because it moves with the Sun as the camera moves around.

A thousand years ago they would have just checked their star chart.

I have been dealing with flat earth shittery for quite some time. I wasted time trying to explain things, I put so much effort trying to reason with them, I wrote articles in relative blogs and so on. In the meantime, I would face one of the following two groups:

The first consisted of people who deeply believed that the earth was flat and there was nothing you could do to persuade them otherwise. The thing with that group is that they were not provocative or trying to force their theory on you. They were plain stupid, as I saw them at the time, but at least they weren't making a fuss.

And then there was the other group. Those who had (recently in most cases) read 2 articles in some pseudoscience blog and viewed a few YouTube videos which claimed that the earth was flat and had thus concluded that they had been enlightened and could now see the truth. This group consisted of stubborn people who had the mind of a 5 year old. But not the plain stupid type, no. They were the ones who were feeling superior, much smarter than "the sheep globers", as they would call anyone who "believed" that the earth was almost spherical. If you tried to reason with them, they would either insult you or would send you videos with "scientific proof" of earth's flatness which were as valid as a 10 year old's driving license. Arguing with them was not only exhausting, but also never lead to any result (other from me being banned from the group or something of that sort).

Then one day the following happened. The administrator of the group I had been following for the most time, in which I had to make more than one bot accounts, since I was getting banned a lot, made a statement. He said that he wanted to thank the "globers" for making a fuss about such groups and going into such trouble to explain that the earth was round. Thanks to them, the flat earth movement had gained a lot of attention the past year... (continuing on next post due to long comment)
>>
>>9154888
Most of this attention was negative, due to people like me trying to persuade flatearther's that they are stupid. But a part of it, smaller, yes, but significant none the less, was from people who had no idea about the Flat Earth movement and got the chance to read about it and joined it. Yes. The people that I considered to be more stupid than a rock in Texas had outsmarted me (one of them at least) and managed to use me, my time and my effort.

What's the conclusion of that story? A friendly advise from someone who spent a lot of time trying to explain something fundamentally true to people who deny it. This advise is: stay away. As long as they are not hurting you (unlike fanatic religious terrorists for example), leave these people be and don't try to reason with them. As long as they can't immediately hurt you (except for the headaches of course), they are not worth your time. Don't try to reason.

Analyze your interests and see if any of them can be developed into STEM. If you haven't any, get to know some STEM subjects to see of there isn't something that you enjoy.
I am like you. I'm not interested in science myself, but reading into philosophy I got interested in logic, so I ended up enjoying math. I still don't like most of STEM, but now I like math, and I can go into banking and make lots of money.

Numbers wouldn't be made up of a unique product of primes otherwise.

Instead of only having 2 * 3 for 6 you could have 2 * 3 * 1 * 1 * 1 * 1, etc.

You go from numbers having a unique product of primes to them having an infinite number of products of primes if you include 1 as prime.

Suppose that [math]a_{o}, a_{1}, a_{2}, \dots , a_{n} \in \mathbb{Z}[/math] are integers. Show that the product
[eqn]\prod_{0\leq i < j \leq n} (a_{j}-a_{i})[/eqn]

That product always equals 0, ergo it is divisible by everything, in particular by n!

Hi, I have a generic microscope that comes with an oculair that can be connected to a pc. However, I have lost the CD software, so I wonder whether there is any other software that I can use for my microscope?

Also, if you hook it up to a PC shouldn't the PC just see it as a webcam? It'd install a generic driver for it and you could use any 3rd party program to view it, like MPC-HC, MPV, or VLC?

This website contains all posible images. There's an image of you having sex with an alien from a distant galaxy, and there's an image of you in the exact moment you die.

If you use a software that can recognize complex shapes, say, a face, how much computer power would you need to find a meaningful image in a reasonable amount of time?

Obviously, doing it manually would take more time than what the Universe will last.

But could automatization reduce it significantly? Or is it hopeless?

Help, /sci/, these numbers are orders of magnitude bigger that I can't comprehend.
