 | YouTube is the number one video-sharing platform in the world with more than 95% of the internet population using it. It provides videos ranging from silly pranks, heartwarming stories, news about the latest global issues, people's personal interests, information about cutting edge science, genuine debates between people who disagree but want to understand each other, lies to serve a political agenda, the ramblings of mentally ill people and everything in between.
YouTube has an algorithm that focuses on overall audience satisfaction, over providing people with a neutral, objective or balanced perspective on the world. It suggests videos based on how users with similar viewing patterns to your own reacted. It personalizes its recommendations based on channels to which you’ve already subscribed. This poses a risk of limiting people's access to information, that they didn't know they would have wanted to know.
I created this topic to exchange informative and educational videos with other people, who might have been algorithmically limited to other content than I am myself. I do suggest to limit this topic to informative and educational content, because there are already enough other topics for fun and questionable stuff.
Although politics and climate change can be categorized as informative and educational, there are already enough other topics debating politics and climate change. Science in general isn't political, neither is (or should) philosophy. Religion is associated with politics, but honest debates on this topic are not political, in my opinion. If you think these subjects are all terribly boring, I don't agree, but then this topic is not for you. That's OK. |

It wasn't all new to me, but it was a good deepening of my knowledge.
He uses the exact same multi-meter that I use at work.
At home I use something that looks like it, but is many times cheaper.
Did you find it for a music related project?
but I was more impressed with his system. It doesn't say much, because there was also a 15 year gap between them. That's no comparison.
The $400 amplifier I bought was great, but I hardly used its potential. I only have 2 speakers of at best moderate quality. It broke, but the vendor had a extended warranty policy for it. I spent another $250 for a newer model. That one sound exactly like the first one on those 2 speakers. I am planning to upgrade those speakers, but it is very low on my priority list. I hardly use that amplifier. When I listen to music, it's on 2 pretty good PC speakers, in my car (which has crap speakers, but optimized for the low power in-car multimedia system), or on my $100 in-ears. I have a Sony WH-1000X M3 headphone laying around, that would provide the best sound, but I hardly use it.
I'm not very picky when it comes to sound. I want to have decent base, decent range, without any rattling, then I'm fine with it. When I hear a good quality system, I recognize that it's much better, but I'm not interested in spending the money to have it.
I can enjoy the music in the quality I'm willing to pay for.
If you are interested in hearing an actual teacher provide a summary of the science of Everything, from the Big Bang to Evolution, Forrest Valkai has done it very well, on a TikTok Live Stream in August 2021.
"This stream covers an awful lot, but is simple enough to be digestible by anyone who wants to understand the actual story of the universe and us creatures who live in it."

A Brief History of Everything
Good video just over 3.5 hours long (3:33:15 minutes).
At 6:30 , Forrest states, "If you're here to push your religion, I didn't come to your church to
teach science, so, please kindly take your religion out of my science
classroom. It's just not necessary …"

He goes on atheist channels to debate believers too. On his own channel he reacts to creationists a lot.
He has a very positive attitude about it and treats true believers kindly and respectfully, but he's not careful with his arguments.

Nikola Tesla was obviously smart, and he discovered some very useful things, like alternating current. He should have been recognized and rewarded for it, but I'm afraid his ambition was stronger than his ability to deliver results. His elaborate experiments didn't help him advance understanding of electricity much. Wireless communication works with electromagnetic waves, but using a Tesla coil to produce them is very inefficient. Others beat him to the theories and the practical applications. His experiments were very expensive, but didn't provide his investors with any return on investment. Instead of inventing marketable applications, like Edison did, he pursued futuristic fantasies, that have never become reality. I think he was foremost a skilled engineer. It's a true genius to created and operate what he did, without electrocuting everyone. If he had collaborated with a theoretical genius, they would have invented everything that others did, based on his wild ideas. Maybe he just lived 50 to 100 too early. He would have done great in our time.

Helping people is indeed not always about money, even if they are lacking money. Some people just need help. If you have the skills to help, that's more effective. Some people are lacking time, if you have the time, you can help with some time. Maybe they have the skills to do it themselves, but they lack the tools, then you can lend them the tools. Maybe they don't have the skills and you have, then you can teach them the skills. Sometimes they only lack the confidence and a little support allows them to help themselves. Some people are just alone and just need a friend.
In this case, they donated time and saved him a bunch of money for a new car. By making a nice video from it, they generate a lot of views, get advertisement money from YouTube, which helps them help the next family. Meanwhile, they might motivate someone to start learning those skills or to help people with the skills they already have.
