Read a great Reddit thread putting historical dates in perspective.

Here are 8 gems.

1/ The moon landing was only 66 years after the Wright Brothers first flight (1903-1969). Within a lifetime, humans went from having limited flight tech to travelling ~239k miles from Earth.
2/ On a related note, Cleopatra (b. 69 BC) lived closer in time to the moon landing (1969) than the construction of the pyramids (~2500 BC).

In fact, some wooly mammoths still roamed the earth when the pyramids were being built.
3/ A really well-travelled person could have potentially met Socrates (470-399 BCE) Confucius (551-479 BCE) and Buddha (563-483 BCE).
4/ Oxford University (1096) is older than Machu Picchu (1450), and it's not even close.
5/ Harvard University was founded in 1636, decades before Isaac Newton developed calculus (mid-1660s).
6/ J.R.R Tolkien (The Lord of The Rings), Otto Frank (The father of Anne Frank), and Adolf Hitler where all present as foot soldiers at the battle of the Somme (1916).
7/ People began actively traveling the Oregon trail (1843–1869) when the fax machine was invented (1843).
8/ While Hannibal was crossing the Alps into the Roman Empire with elephants, the Great Wall of China was in its initial construction phases.
Anyways, Happy New Years.

To further put the 1969 moon landing into perspective, look at Apollo 11’s Apollo guidance computer (ACG).

Compared to ACG:

▫️a TI-73 calculator has 140x the processing power
▫️an iPhone 11 has 100,000x the processing power and 7,000,000x the memory

A lot of replies note that Gore Vidal’s 1981 book “Creation” is about someone who “travels the known world (6th-5th BCE) comparing the political and religious beliefs of various empires”.

The protagonist meets Buddha, Confucius and Socrates.

wow, found a rare interview of a DeepSeek co-founder talking about his first AI startup exit a few years ago
Jian Yang is my 2nd fave Asian founder who created a food-related product.

The 1st is David Tran, who built Sriracha (great on hot dogs) into a $1B brand using $20k of gold bars he snuck out of Vietnam in milk cans.

I tell the full story in this podcast: podcasts.apple.com/us/podcast/caf…

PayPal’s bland logo redesign was inevitable

If you are the person that did the un-aligned letters for the previous eBay logo, please contact the research app team. We are huge fans of how un-aligned the “e” is with the “y”.Bearly.AI
This article offers up reasons for popularity of simple font logos (mostly Sans Serif):

Berkshire Hathaway board member Chris Davis once asked Charlie Munger why Costco didn’t drop the membership card.

Let anyone shop and raise prices by 2% (still great value), thus making up for lost membership fees (and more).

Munger said the card is important filter:

▫️“Think about who you’re keeping out [with a membership card]. Think about the cohort that won’t give you their license and their ID and get their picture taken.

Or they aren’t organized enough to do it, or they can’t do the math to realize [the value]…that cohort will have a 100% of your shoplifters and a 100% of your thieves. Now, it’ll also have most of your small tickets.

And that cohort relative to the US population will probably be shrinking as a % of GDP relative to the people that can do the math [on Costco’s value].”▫️

I have a membership but have been guffing on the math for a few years tbh. They keep telling me to upgrade from Gold to Business but I’m too lazy (even if the 2-3% Cash Back on Business pays back after a few trips).

This is a long way of saying Costco’s membership price hike effective today — its first in 7 years — is annoying but when I decide to do the math in a few months, it’ll be worth it.

Chris Davis’ remarks from this episode of The Knowledge Project: open.spotify.com/episode/6fJYHF…Image
Anyway, here is something I wrote about Costco’s $9B+ clothing business my affinity for Kirkland-branded socks and Puma gym shirts. readtrung.com/p/costcos-9b-c…
Two notes:

▫️Meant “Executive” (not “Business”) membership
▫️Chris Davis was doing a pure thought experiment. Costco membership obvi high margin (on~$5B a year) and accounts for majority of Costco profits. Retail margin is tiny on ~$230B of annual sales (Costco would need like another $150B+ from letting anyone shop to make up membership profits)Image

Explainer video on science of why the 400m sprint is considered the most painful track & field event.

And why “no person on the planet can run the 400m all out from start to finish".

The race pushes the way the body creates energy to the limit:

▫️0-50 meters: ATP-CP (energy system for very short and explosive movements; used up after 5-10 seconds)

▫️50-200 meters: Anaerobic glycolysis (burns glucose without oxygen, leading to lactic acid buildup and muscle fatigue)

▫️200-300 meters: Aerobic energy (uses oxygen to break down glucose, but cannot keep up with the demand)

▫️300-400 meters: Anaerobic energy reserves tapped while aerobic energy is too slow to fill the gaps (lactic acid buildup is going HAM)

Track athletes can pace for longer distances and shorter ones are just over quicker (obvs).

The Olympic record is a blazing 43:03, set by South African runner Wayde van Niekerk in 2016 (and 2024 Final race is tomorrow).

***

Full video from Outperform:
Usain Bolt ran the 400m early in career but then said training was “too hard”.

The 400m Hurdles is a world of pain too for similar reasons — Vox has a good vid on it:

Here is a great breakdown of Wayde van Niekerk’s record run:

The 400m is also tough because you don’t get the benefit of an absolute baller like Bottle Klaus keeping hydrated
