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.
Animals first sensed light 540 million years ago, triggering an evolutionary acceleration known as the Cambrian explosion within 10 million years.
It is estimated that half of all cortical activity in the human brain is involved in visual function, underscoring vision's central role in intelligence.
Cognitive neuroscience literature shows that by age 6, humans can recognize tens of thousands of different object categories — far more data than early AI systems were trained on.
Only about 3% of FDA-approved drugs have genuinely unclear mechanisms of action, making an unknown mechanism a meaningful early red flag for any compound.
Even compounds that clear preclinical testing often fail in humans: 30 to 50% of drugs entering phase 1 trials do not advance to phase 2, frequently because human behavior differs from animal models.
More than 80% of published BPC-157 research comes from a single academic group whose researchers have IP and commercial interests connected to the molecule, limiting independent replication.
Roughly 100 peptide drugs are already FDA-approved, about 150 more are in clinical trials, and 600–700 are in preclinical development, underscoring the legitimacy of peptide science broadly.
The scientist who discovered BPC-157 refused to disclose the screening method used to identify the compound and has never fully published the parent protein sequence — what Peter Attia calls 'scientific trust me, bro.'
The brain's visual, auditory, and motor cortices light up nearly identically whether an experience is real or imagined, making visualization a form of actual neural training.
