About Me
I've always loved the feeling of opening the mailbox and finding the latest issue of a magazine you've subscribed to for years. Growing up, my favorites were ESPN The Magazine and Architectural Digest. These days, we're constantly sharing videos, photos, and opinions - so why not our own magazines? Qorrum is a platform where anyone can create and share their own monthly magazine, and explore ones made by others. Mine will usually center on cumulative knowledge, major tech developments, and general learnings - though each issue will take a slightly different shape!

America’s Phenomenal Geography 

Jamie Dimon once said: “America has the best hand ever dealt of any country on this planet today ever, okay. And Americans don’t fully appreciate what I’m about to say. We have peaceful, wonderful neighbors in Canada and Mexico. We’ve got the biggest military barriers ever built, called the Atlantic and the Pacific. We have all the food, water and energy we will ever need.”

Michael Gridley posted a great Twitter thread expanding on the tremendous geographic hand the US has been dealt a few takeaways below:

From 16,000 to 32

At any given time there are 16,000 high school quarterbacks, 32 starting QBs in the NFL (~12 very good ones, ~4 great ones).

"American Kings", a new book by Seth Wickersham, explores the question of what these 32 have in common that the other 15,968 don't.

A few takeaways below - what I found most interesting was that once a minimum athletic baseline is reached, greater intangibles (work ethic, resilience, adaptability, etc.) were more valuable than greater athleticism.  

Athleticism - Baseline minimum bar for

  • Height: 6’ to 6’5”
  • Hand size: 9+ inches
  • Weight: 190-230 lbs
  • Arm strength: 50mph+ top ball speed 
  • Throwing range: 50+ yards
  • Accuracy: 60%+ in HS and College
  • Quick release: under half a second
  • Baseline Lateral Quickness

The Invisible:

  • The measurable (arm strength, speed, pedigree, flash you can see) is overvalued; the invisible is undervalued (endurance, intelligence, adaptability, self awareness, confidence)
  • Beyond baseline athleticism, the invisible intangibles had the biggest impact on quarterback success.

The Environment:

  • Coaching quality (think 2 of the great QBs in Tom Brady & Patrick Maholmes getting coached by 2 of the greatest coaches in Bill Belichek & Andy Reid)
  • Coaching stability (system stability allows cognitive mastery and confidence)
  • Talent (offensive line to block, receiving talent, running talent)
  • Opportunity (QB slot opening up)

The Basics:

  • “The game winning drives of Montana, Elway, Brady: what stood out was how mundane and obvious and simple they were. Like move the chains with slight throw to the running back.”

Double Click:

  • Tom Brady is arguably the best football player of all time.
  • Right before his first start as a QB in high school, he ran to his dad and said he "couldn't do it" because he had "forgotten how to throw". His dad calmed him down.
  • Fast forward to his last year in New England 20+ years and 6 Super Bowls later. At the front of his playbook he’s written himself these self affirmations like “you’re the man”, and “you’re built for this”, “you love the big moments”. He’s written these things that he reads every day. 
  • Playing in front of tens of thousands of people with many more watching and counting on you, failing repeatedly as all QBs do, and maintaining the confidence to make a tight throw under pressure takes a special combination of internal and external support.

Singing in the rain

At a concert I came across the opener John Butler. He played this song live - I’d never heard it before, but it’s about as great as any guitar piece I’ve ever heard. Two quotes from YouTube comments: “this song is probably the most perfect song ever made”, and “If I was forced to keep only one guitar performance on entire Internet and delete everything else I will keep this one”.

In June my family took a vacation to Belgium, Germany, and Switzerland - first time for me in all 3 places!

Couple highlights of a great trip (not in pictures: me falling in the plane and twisting my ankle and knee, getting crutches for the rest of the trip…but lots of nice Belgians/Germans/Swiss helping me get around)

In Switzerland I got to visit the “Large Hadron Collider” center and learn about one of the most impressive engineering feats ever created.

The LHC accelerates particles to near the speed of light and smashes them together to recreate conditions similar to those just after the Big Bang. By analyzing the resulting particle collisions, scientists explore fundamental questions about the universe.

Here’s a few LHC facts that show the incredible things people can build:

Where it is:

  • 17 miles in circumference straddling the border between France and Switzerland
  • 100s of feet underground

Speed

  • Particles are accelerated to 99.999999% the speed of light
  • Means they make over 11,000 revolutions per second around the 17 mile circumference

Temperature 

  • Cooled to about negative 450 degrees F, near the coldest possible temperature possible in the universe

Massive Components

  • Over 12,000 components that each weigh up to 28 tons
  • One of its detectors weighs 14,000 tons

Data

  • Experiments generate more than 30 petabytes per year (equivalent to over 1 million blue ray disks)

Effort

  • Took a decade to build
  • 10,000 plus people from over 60 countries helped build it, with over 2,000 staff keep it running and many more scientists all over the world contributing to its experiments
  • Constructed with incredible precision and using theories built up over centuries (like the ones written in this sculpture in front of the center)

AI - a few interesting snapshots from the month:

Miscellaneous - June 2025

Reducing sleep noise matters a lot for your health, sleep somewhere quiet 

The future of remote vs in-office work is still in flux and will not be homogeneous

Cool concept - used it on a trip recently and found it really helps get a feel for a new place quickly 

Cabbage -> Basketball, Apple -> Newtonian Physics, … what produce-inspired ideas have you had recently??

Finishing my June 2025 issue with these wise words:

1) Steph Curry is very good at basketball 

2) What jumps out to me in this is an analogy to hiring. The difference one person can make on how your team/group/company operates can be massive and the difference between excellence and a mess. 

Science & Technology 

Self-driving cars are here (the future is here just not evenly distributed) - every week one quarter of a million Americans take a Waymo in SF, Phoenix, Austin, or LA.

A self driving car will be the safest car on the road - every year 1.2 million people die in car accidents, while Waymo has had far fewer crashes than human drivers and no fatalities.
