The odds against him were staggering: he was an unknown doctor with no formal research background, working in a sweltering room provided reluctantly by a skeptical department head. ‎ ‎Facing a total lack of steady institutional funding, Banting had been forced to sell his medical equipment and spend his very last pennies just to keep his independent project alive. To the established scientific elite of the era, the idea that this desperate, broke young man could cure one of history’s most terrifying medical death sentences seemed entirely impossible. ‎ ‎To unlock his impossible goal, Banting—alongside his young assistant Char...

Before a polymer breaks, invisible events are already happening inside the material: 🧬 Polymer chains begin to move and rearrange ⚠️ Weak points become stress concentration zones 🔍 Microvoids and small defects start to develop 📈 Damage slowly accumulates under mechanical loading . By the time we see a crack… The material has already been changing for a long time. This is why understanding polymer failure is not only about observing the fracture surface. . It is about understanding what happened before the fracture. The real question is not: "Where did the polymer break?" . The deeper question is: "Why did the material allow the damage to grow?" . From product design to failure analysis, polymers always leave clues before they fail. . A fracture surface is not just a broken part. It...

The old way was rigid and led to lives of boredom and restraint. It worked for some people, but it didn't for many others. However, people don't realise that's not the way it needs to be. After all... ❌ Oracle have laid off 30,000 people this year. ❌ Amazon have eliminated 16,000 roles this year. ❌ Meta have announced job cuts of 8,000 this year. Following the linear path no longer provides the security it used to. Careers are not linear. I've learned this in my own career. I did the degree, the internship at IBM, the 'failed' first job. Backward steps and roundabout decisions... To where I am now: Co-Founder of LeverBrands. $2m ARR business in 2 years since launching. Plus, a personal brand with 105k+ follower...

𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 𝐓𝐡𝐞 𝐀𝐜𝐜𝐢𝐝𝐞𝐧𝐭𝐚𝐥 𝐈𝐧𝐧𝐨𝐯𝐚𝐭𝐢𝐨𝐧: 𝐖𝐡𝐞𝐧 𝐂𝐮𝐫𝐢𝐨𝐬𝐢𝐭𝐲 𝐂𝐫𝐞𝐚𝐭𝐞𝐝 𝐍𝐲𝐥𝐨𝐧 Nylon fiber was developed by a DuPont research group headed by the brilliant chemist Wallace Carothers. His team was tasked with finding synthetic versions of natural products such as silk and rubber. Toward that end, they synthesized several polymers in the polyamide family (later trade named Nylon) but were not impressed with the properties of these materials. Being chemical researchers, they did not explore the processing capabilities of the new materials. The focus of their work shifted toward polyester chemistry. In 1934, a member of Carothers’ group, chemist Julian Hill, noticed that he could draw stands of fiber by prodding a moist lump of polymer with a glass rod. These fibers were intriguing because initially, they were extremely stretchy. One day, Carothers was away from the lab and the staff was free to experiment in an enter...
