Logging the World - Oliver Johnson

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.

I know! And now we have to wait? Rude

[@prabhureubenthomas6052]

Yep same here

It’s really good advertising

Can you please share the link to it ? Thanks in advance

[@jujt2258]

⁠@@randomgeek9385I don’t think you can post links, it’s just the first minute of this lecture

Lmao, how did some random short get me watching a full maths lecture

[@9WEAVER9]

Embrace it!

[@AdityaSenarchadii]

First time?

[@___James___]

Yeah ikr

[@7riX7er]

It took me longer to open the link on the description of the short than multiplying the two numbers

[@eazystudio]

Same!

I can't believe I'm excited to watch a math lecture -- and adding it to my calender being a biology person. I'm a nerd

1:18 is where it continues from the KZbin short

[@brattwurst1979]

bro that "you've come to a maths talk on valentine's so im hoping you've heard the word exponential before" 🤣🤣🤣

[@maxpetrov4288]

You've come to a math lecture on valentines Day - oh, that is sooo me

[@luisricardolopezvillafan3713]

A nice example of salesmanship for a math lecture

[@Player-st3nu]

For people here from the KZbin 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

[@lusvd]

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

[@Aquamarinehoney]

The title won me hands down👍

[@smurphete]

9:23 He explains why they're the same complexity...they're not.

Thank you for unveiling the COVID-19 inaccuracies-there are many

It was actually John Tukey (also at Bell Labs) who invented the word "bit," but Shannon used the word in a 1948 paper.

Brought here by the clickbait, didn’t stay much longer 😂😴

[@aleyziondder252]

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.

[@pma1377]

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!

[@katmai90210]

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?

[@JeffMTX]

That was the politicians (or somebody) DECEIVING people. And why?

[@geomorph]

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]

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.
