Completed exercise: porosity distribution analysis using basic statistics, histograms, and cumulative distribution functions. In this work we used descriptive statistics to summarise porosity values, built histograms to visualise how frequently different porosity ranges occur, and constructed CDFs to understand exceedance probabilities and cut-off thresholds. This simple but powerful workflow helps compare rock samples, check for normal or skewed distributions, and make data-based decisions about which intervals are more suitable for flow, storage, or further detailed testing.

In 1956, John Bardeen arrived in Stockholm as a quietly spoken engineer who had just helped change the world. The transistor was no longer a clever lab curiosity; it was becoming the seed of a new electronic age, and Bardeen was there to accept the Nobel Prize in Physics alongside William Shockley and Walter Brattain. At the ceremony, amid all the formality, the King of Sweden noticed something surprisingly ordinary: Bardeen’s family was not fully there. With a teasing tone, the King asked why he had not brought his children to share the moment.

Bardeen’s reply, as the story is remembered, was pure Bardeen: calm, dry, and slightly mischievous. He said he would bring them “next time.” It sounded like a polite joke, the kind you say to defuse attention and move on.

Sixteen years passed. Science moved forward, and so did Bardeen. In 1972, he returned to Stockholm again, not as a one time laureate, but as the same person being honored a second time, now for the BCS theory that explained superconductivity at a fundamental level, shared with Leon Cooper and Robert Schrieffer. This time, when the doors opened and he stepped into the spotlight, he did not come alone. He brought his family with him. The punchline landed years later, perfectly timed: the man who had promised “next time” had meant it.

In the last decade of Ada Lovelace’s life, her fascination with probability and risk slid into a serious habit of betting on horse races. Several biographies describe her as believing that careful analysis of past results, odds, and patterns could be turned into a repeatable “system,” something like an early predictive model that would let her beat the bookmakers.
As the bets grew, the losses did too, and the gambling stopped being a clever experiment and became a financial trap. MacTutor notes that she pawned some of her jewels to finance the betting and that she was still in debt when she died.
A widely repeated anecdote, traced by popular historians to Julia Markus’s biography, says she once lost £3,200 on a single race at the Epsom Derby, a sum that would correspond to “hundreds of thousands” of pounds in today’s money depending on the conversion method.
Some retellings add a dramatic detail that she and Charles Babbage tried to develop a mathematical formula for betting, partly to raise money for work connected to the Analytical Engine, and that the scheme failed, leaving her with large debts.
But there is an important historical caveat: Stephen Wolfram, reviewing the evidence, argues that the more extreme gambling stories and claims of a formal betting scheme are often exaggerated, and that there is no solid evidence that she and Babbage actually built a working horse betting algorithm.
Even with that uncertainty, the episode remains revealing because it shows the same mindset that made her extraordinary: the belief that messy real world outcomes might yield to mathematics, if only the right structure and the right data could be found.

At Los Alamos during the Manhattan Project, security was often more “procedural” than truly robust, and Feynman’s curiosity locked onto that gap. He first noticed that sensitive papers were sometimes kept in ordinary filing cabinets, and he learned to pick the simple locks to get what he needed, largely as a puzzle and a prank, not to steal anything. When the lab switched to filing cabinets with combination dials, he treated them as an even better challenge and kept experimenting until he understood their quirks. In one account, he explains that if a cabinet was already open you could often infer the last two numbers of the combination, and with those in hand the first number becomes a small search, so opening the cabinet could take only a few minutes.

One of the most famous episodes happened when he returned after the war and needed a document on a weekend. He went to the office of the declassification officer, Freddy de Hoffmann, and while waiting he started “testing” the combination lock. Following the kind of tricks described in safecracker lore, he looked for a written clue and spotted a sheet where “pi = 3.14159” was scribbled, tried variants, failed, then made a sharper psychological guess: a mathematically minded person might use the constant . He tried 27-18-28 and the cabinet opened, and he discovered multiple cabinets were set to the same combination.

After taking the document he needed, he left a pointed calling card to prove the breach and embarrass the complacency, writing a note like: “I borrowed document no. LA4312 — Feynman the safecracker,” and in other cabinets he left extra notes signed “Wise Guy” and “Same Guy” to underline that identical combinations made the “other” safes no harder at all. When de Hoffmann later found the bright note, the story goes that he turned visibly pale and panicked, suddenly realizing how exposed the “top secret” material really was.

Napoleon had just received Laplace’s huge book on celestial mechanics. He flipped through it and asked: “Why is there no mention of God?” Laplace calmly answered: “I had no need of that hypothesis.”

Before 1706, π didn’t have a name! People just called it "the number that gives the circumference when multiplied by the diameter" (way too long, right?). Thankfully, Welsh mathematician William Jones introduced the π symbol, making life easier for everyone!
