In June 1752, Franklin flew a kite with a sharp wire attached during a thunderstorm in Philadelphia, successfully drawing electric sparks from a cloud and proving lightning was an electrical phenomenon.

Richard Robinson described Franklin's kite experiment as the great symbolic moment of the Enlightenment's project of freeing humanity from needless terrors, and Tom Holland agrees it is Franklin's most significant scientific achievement, even if he lightly mocks it as 'science is fun' for eight-year-olds [1] — Tom Holland "In June 1752, Franklin flew a wire-tipped kite into a thunderstorm in Philadelphia, drew electric sparks from a cloud, and proved lightning…" 27:56 . In June 1752, Franklin flew a wire-tipped kite into a Philadelphia thunderstorm with his son William, drew electric sparks from a cloud, and concluded that lightning was a physical electrical phenomenon — not divine wrath. The practical consequence was the lightning rod, which Franklin refused to patent so that it could be freely adopted to prevent city fires. He also invented bifocal spectacles in 1784, identified and named the Gulf Stream, demonstrated surface tension by pouring oil on a rough pond on Clapham Common, invented weather forecasting by analysing East Coast storm patterns, and — as a child — designed hand and foot flippers for swimming. A Russian scientist who tried to replicate the kite experiment a year later was electrocuted and killed, underscoring the genuine danger Franklin had courted.
In June 1752, Franklin flew a wire-tipped kite into a thunderstorm in Philadelphia, drew electric sparks from a cloud, and proved lightning was a physical phenomenon — not divine wrath. A Russian who tried to replicate it a year later was electrocuted and killed. The lightning rod that followed kept cities from burning.
A year after Franklin's famous kite experiment, a Russian scientist attempted to replicate it and was electrocuted and killed, underscoring how dangerous the experiment had been.
The widely cited ego-depletion model — the idea that willpower is a finite resource that gets depleted — failed to replicate in follow-up studies.
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.
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.
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.
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.
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.
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.
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.'
