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.
Here after getting edged by that ig reel
I know! And now we have to wait? Rude
Yep same here
It’s really good advertising
Can you please share the link to it ?
Thanks in advance
@@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
Embrace it!
First time?
Yeah ikr
It took me longer to open the link on the description of the short than multiplying the two numbers
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
Nobody fucking asked
@@user-un5wf5ou4h yay
And No one asked you to be rude and comment. You seem mentally ill
@@user-un5wf5ou4h I did actually. I asked
For people here from the CZcams 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
You've come to a math lecture on valentines Day - oh, that is sooo me
A nice example of salesmanship for a math lecture
The title won me hands down👍
9:23 He explains why they're the same complexity...they're not.
🤓thenks
Thanks
1:18 is where it continues from the CZcams short
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.
Click bait ig brought me here
Can't believe I am here too
New Hampshire, U.S.A.
Yes I want to know how to beat look at the problem to solve it more efficiently.
what does he use to make slides? does anyone know?
LaTeX
Overleaf
Its a latex package called beamer
started with an ig reels and now I'm stuck for 48 minutes on math lecture...
Pam Beesly brought me here but Oliver Johnson kept me ❤
🗡🍎🫗

Another NERD from NH 🙂👋
I am so lost, can you please tell wdym by NH
Thanks in advance

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