Top quark: 19 in 6–12 months vs 1/second
Fermilab's 1995 top quark discovery paper had just ~19 clean candidates collected over 6–12 months; the LHC now produces a top quark every second.

What E=mc² Actually Means: Turning Energy Into Matter
E=mc² isn't just a formula about bombs — it means energy and mass are directly interchangeable. Smash two particles together with enough energy and the collision can literally create new particles from pure movement energy. Every collider in history is a machine for converting motion into matter.
100,000 protons per antiproton
At Fermilab, scientists had to smash 100,000 protons into a target to produce just one antiproton, illustrating how extraordinarily difficult antimatter production is.
1 billion collisions/sec at LHC
The Large Hadron Collider at CERN produces approximately one billion proton-proton collisions per second, of which fast electronics and computers select about 1,000 per second for detailed analysis.
How the LHC Finds One Interesting Collision in a Billion
The LHC produces a billion collisions per second, but 999,999,000 of them are completely boring. A cascade of fast electronics and computer farms filters that firehose down to 1,000 events per second worth storing. Graduate students then sift those for the handful that might be a Nobel Prize.

Ego depletion research failed to replicate
The widely cited ego-depletion model — the idea that willpower is a finite resource that gets depleted — failed to replicate in follow-up studies.
5,000–7,000 thoughts per day; recall ≈ 0
Humans are estimated to have 5,000–7,000 thoughts per day, yet can recall essentially none of them afterward, highlighting why in-the-moment emotional tracking matters.
Wandering mind = unhappy mind (Harvard study)
A large Harvard study found that a wandering mind is an unhappy mind — people report greater happiness when their attention is tethered to the present, even if the task is unpleasant.
Microplastic overestimate: gloves contaminated tests
A key study finding that we have a 'credit card's worth of plastic' in our bodies was likely skewed because researchers used nitrile gloves that shed plastic particles onto the microplastic detector.
Hyperactive amygdala + frayed PFC link
Emotionally sensitive people have a hyperactive amygdala, an underactive prefrontal cortex, and a frayed connection between the two — making emotional regulation structurally harder.

Rejection sensitivity can be observed as early as age 2 or 3, suggesting it has strong developmental and likely genetic roots.
Mindfulness reduces brain activation — Yale study
A Yale study found that non-judgmental observation of emotions — without rushing to resolve them — reduces activation in the brain, making it a powerful regulation tool.
Psychological immune system works strongest on irreversible decisions
Dan Gilbert's research found that the psychological immune system — the brain's ability to justify and find satisfaction in choices — activates most powerfully when a decision is perceived as irreversible.
Maximizers earn more but are less happy than satisficers
Barry Schwartz's research found that maximizers — people who try to optimize every decision — tend to achieve objectively better outcomes but report lower happiness than satisficers who choose 'good enough.'
