How Edmund Halley used big data in 1686

[@qwertyTRiG]

You're also growing as an interviewer, Simon. That's a skill in itself.

I've always loved Keith from objectivity - nice to see him talking with actual scientist

This is such a cool discussion and methods for presenting the information! I Would love to watch a video on the evolution of scientific papers. There was some discussion on comparing Halley’s diagrams to those of today as well as the impact of the journal. However, since it is mentioned that most of these people did not make a living through science, I would be interested in learning how people got involved in science and what was threshold for something to be considered a sound contribution to the field and how that evolved.

I like how slipped "...nice name..." into that ad. Also the rest of the video. I liked that too!

[@Anegative]

Another fascinating video, well presented and Keith was amazing

[@harryslaughter9393]

Now I need to see a Simon Clark X Objectivity video. (There is also a lack of atmospheric physics on Sixty Symbols…. Time to pester Brady)

[@CatherinePryde]

First sound of "Halley" and then keep watching this urge me so much to come back to Firmament to re-read a bit what I went through and continue to absorb the rest. But other than that, this video warms up in me once again a lot of respect to scholar people of that time who kept pushing their own boundaries so much so that we now can stand on the soulders of giants and move forwards. Even the term "fellowship" itself sounds so much more like an active engagement to pursue something greater than just a position one might ought to look for while embarking a research career. Glad to see another work from you again Simon and thank you for making this saturday much brighter and pleasant.

Simon, you're living my dream! I've always wanted to go to the Royal Society and explore the library. I have a couple of papers in one of their open access journals (not the Philosophical Transactions! That's very prestigious and invitation-only journal). I'm afraid that's as far or as close as I'll ever get...

7:28 For anyone wondering why the wind speed must decelerate when moving away from the axis (and towards the equator), this is because the circumference at the decreasing latitudes (both north and south) increases as the air moves towards the equator. The wind therefore moves over an increasingly large cross-sectional area (proportional to the latitude) and the speed of the wind towards the equator must therefore decrease (inversely proportional to the latitude) in order to maintain constant total linear momentum over latitude. I figured this myself, but I am pretty confident that I am right. Please correct me if not.

It's always a pleasure to hear Keith talk ☺

[@EtecMax]

I was so happy to see him in the Video. Keith is the best.

[@AMoon-xq4ry]

This video was great, thank you for your work.

My fiance picked up a free VHS copy of Muppet Treasure Island a bit ago and we watched it on a snowy evening. He never saw the movie growing up, whereas I did and I knew the song Cabin Fever (where the ship and crew are stuck in the middle of the ocean for weeks) would be one of the goofiest ones in the film, he went along with it, knowing it's a kids movie (where a guy dies at the beginning). That had us talking about Trade Winds and the Doldrums and got me doing an extensive dive about them on Wikipedia (I took a Physical Geography class in college to complete my degree, which I loved, but it didn't hurt to brush up on them again). I didn't know that the Doldrums can still cause problems for sailors to this day if they choose to sail without any additional power to get them through certain parts of the ocean at some points in the year. That was pretty interesting to find out in 2022!

[@SerromayD]

I’m loving this upload frequency!

[@CZ-PC]

Fantastic video as expected from you.

[@hiddenrainbow12]

I love videos that have to do with the history of science. Great video, Simon!

[@cleon_teunissen]

At around 7:45 you remark: " [...] I know it's a bit mind melty; this idea took a long time to catch on [...] I want to give a general comment here: to visualize the interaction between the Hadley cells and the Earth's rotation you have to keep track of motion in three spatial dimensions. It appears that that is not just a bit more demanding than keeping track of motion in two spatial dimension; people find it a _lot_ more demanding. (Which I assume is why you added the apologetic 'a bit mind melty') Playing video games requires keeping track of motion in two spatial dimensions, and people do that with ease. But in physics there are those two fields of fluid dynamics on the rotating Earth: meteorology and oceanography. (Referred to with the inclusive acronym GFD, Geophysical Fluid Dynamics) I get the impression: even to GFD scientists who are proficient with the mathematical formalism the visualization remains a demanding task. Evolution has endowed us with natural ability to move around. We don't need to think to dash around and remain upright. But bipedal robots struggle immensely with walking (judging by the 2015 DARPA challenge videos). It's a hard problem, and evolution has _totally_ solved it. But it appears that when it comes to keeping track of motion in three spatial dimensions we are doing no better than bipedal robots trying to walk. (Because of the interest I take in the subject: I have created a bunch of simulations that show, side by side, the non-rotating system and the rotating system.)

Great content 👏

[@maroon3353]

Quite informative... Best video... Keep up the streak brother 🔥

[@wiild9088]

Fantastic! Great video and great interview.

[@Mergle_]

I have to say, your book is brilliant. I absolutely love how to communicated the history and development of the science in an intriguing narrative. If anyone is wondering if they should buy the book, please do. Its an amazing read and 100% worth your time.

[@H1289-h8o]

I liked it but wasn’t what i was looking for

[@DirtyPoul]

@@H1289-h8o What do you mean?

[@Flora_737]

Great video man

[@ericdanielski4802]

Nice video.

[@dingus153]

It's so weird seeing Keith outside of an Objectivity video

[@catheosto]

Super interesting ... I still don't get how they managed to measure things and get the data at 17. century. Crazy.

[@Ajan-X]

Simon, please tell your sponsor that it is impossible to re-join with your code when i have a registered account at curiosity stream (even though it has been inactive for years).

[@luaiderar6600]

These videos are great, I don't get why they don't get that much views

[@theoricer]

Cool

[@MrAlexs888]

not first

[@akeel_1701]

That guy looked a bit like Bill Nighy to me

[@PortugalZeroworldcup]

Dubai advertisement before this

[@someroboticpizza]

hmm yes informative and cool

[@iseriver3982]

Ethiopia is a lot bigger than I remember.

[@esgee3829]

gonna be some hate from the ichthyologists in the comments now

[@rickvrieling]

Goodday

[@jonkim5600]

Not second

[@LeanAndMean44]

Really very interesting. Especially useful as a distraction from the war in Ukraine…

[@lodestone8736]

scientist back then are truly a different breed. voyage across the ocean and collecting a ton of data and managed to formulate nature phenomenon with limited technology.
