During the pandemic, you may have seen graphs of data plotted on strange-looking (logarithmic) scales. Oliver will explain some of the basics and history of logarithms, and show why they are a natural tool to represent numbers ranging from COVID data to Instagram followers. In fact, we’ll see how logarithms can even help us understand information itself in a mathematical way.
The solution to the two maths questions puzzle occurs from 9.20 onwards, though the fuller explanation starts from the beginning of the lecture.
Oliver Johnson is Professor of Information Theory in the School of Mathematics at the University of Bristol. He has regularly appeared on radio and is the author of the book Numbercrunch (2023), which is designed to help a general audience understand the value of maths as a toolkit for making sense of the world.

For people here from the RU-vid short : the explanation is about how you can use logarithms to shortcut difficult multiplication. Without taking calculus this will be hard to understand but basically it’s just finding similarities or common pairs of/in numbers, then solving. 9:10 he talking about the simple 2 to the 2 x 2 to the 3 = 2^5. Numbers multiply but logs add, and addition is usually easier than multiplication. Simple enough. The short was misleading tho lmao

yep the short is misleading because it exploits the fact that the numbers are special in that they are both exponents of 2.

Now I really believe I have trauma for math. They are always lying math is easy you say? Or is it that this people only capable of speaking in numbers not words. They just shifted from using proper words to struggling to explain real quick cause they are not focusing on the delivery (easy to get the message out) instead they hop from point A to C. I can't see the relation just click bait.

Such a messy talk... Who is this intended for? You're explaining what a log is and 2 minutes later you introduce PDEs? The content is very good but I think it could have been delivered a bit better!

in the same fashion of me writing a comment before i've watched the whole video, i'll head straight to my doom by doing just that: - Extremely disappointed. Came here expecting a video about logging the world's actions or some things about logging trees efficiently, got treated with a story about logarithms. - Convincing someone seems unnecessary, i mean if you think about it, you'd only need to convince someone of something when you don't know it yourself, but for some stupid reason, you decide to attempt at gathering more people in something you don't really know, which kinda means you're intentionally misdirecting them or if we were to be more prophetic "leading them astray". So the question is why would you do that? i mean if you knew something and you just wanted to pass that information to someone because you'd believe it would make their life better, you'd do simply that. You wouldn't really need to convince them would you?

The irony is that even before reading to the end of your comment, it was possible to guess that it was going to be fairly witless and miss the point of the lecture entirely. As it did.
@katmai90210
@katmai90210 15 дней назад
well, you seem to have it all figured out. i mean most definitely i probably missed the point of the lecture considering i got pretty annoyed mid-way and just closed it, so yes, you're right. whatever other point might have been made by the end of it, the chance of it being heard got nulled by the behavior which prompted the closing of the video. can't say i am a smart man. but on the other hand, don't let that fact deter you from perfecting the art of deepthroating cocks.
