The temptation to recast life’s mysteries as quantum in nature is about as old as quantum mechanics itself. In a 1929 lecture, the quantum pioneer Niels Bohr made the vague but enticing statement that quantum mechanics, which at the time was just starting to find its mathematical footing, “may perhaps be of decisive importance, particularly in the discussion of the position of living organisms in our picture of the world.”
Bohr’s contemporary Pascual Jordan spent several decades writing on 𝘘𝘶𝘢𝘯𝘵𝘦𝘯𝘣𝘪𝘰𝘭𝘰𝘨𝘪𝘦, or quantum biology, arguing that life has a unique ability to amplify the strange indeterminism of the quantum world to macroscopic scales, and claiming this as the basis of human thought and free will.
These early proponents of quantum biology sought explanations for the puzzling properties of life at the classical scale in the counterintuitive laws of physics at the quantum scale.
Since Bohr’s day, researchers have hypothesized that quantum effects are at play in a variety of biological phenomena — including the magnetic sense that helps birds navigate and, more speculatively, human consciousness — with varying degrees of empirical support.
But at this point, there’s still no definitive proof for any long-lived quantum coherence with a biological function.

@yeo_sage Exactly! Seeing Togashi produce such a gripping succession arc without arguably the main characters, yet develop so many endearing others has revealed to me why I love hxh so much
Science is quite unforgiving : I am regurlarly led astray when I look for the thrill and satisfaction of discovery/a beautiful proof, and not discovery itself. Being human is believing I can entertain this purely logic mental image, when I am in fact biased at every step
Making advanced chips requires more than advanced lithography.
It takes metrology, inspection and computational lithography working together – from R&D to high-volume manufacturing – to keep chipmaking economical.
That’s holistic lithography. Watch the animation for more. 👇
This is probably the clearest example of an actual academic collapse.
Weiss entered MIT in 1950, initially studied electrical engineering and then transferred to physics. During his third year, a painful romantic breakup overwhelmed him.
In his own Nobel autobiography, he states plainly;
“I failed all my courses at MIT and had to leave as a student.”
He was no longer progressing toward a degree. He returned to MIT not as a student but as an hourly electronics technician in Jerrold Zacharias’s atomic-beam laboratory. He punched a time clock and worked alongside machinists and laboratory technicians.
That apparent demotion became his real education. Weiss learned machining, sheet-metal work, soldering, welding, electronic design and the improvisational craft of experimental physics.
Instead of merely solving prepared textbook problems, he helped graduate students construct the instruments required for their research and worked on an early caesium atomic clock. With Zacharias’s support, he eventually completed his undergraduate degree and entered graduate school.
Decades later, Weiss became the central experimental architect behind laser-interferometric gravitational-wave detection.
He shared the 2017 Nobel Prize in Physics with Kip Thorne and Barry Barish for decisive contributions to LIGO and the observation of gravitational waves.

Chemistry laureate Brian Kobilka learnt about teamwork and management from his father at a early age:
"My first job was slicing and packaging bread for sale at local supermarkets. Working at the bakery gave me the opportunity to see my father in action. The bakery was operated by my grandfather and great uncle before World War II. When my father returned from service in the army he took over the management and started to expand the bakery from a simple storefront business to one that supplied fresh baked goods to local supermarkets, restaurants and schools. The bakery was a relatively complex small business that prospered by producing a large variety of excellent baked goods including breads, pastries, cakes and candy. To make all of this work, my father had to be able do every job in the bakery, because when someone called in sick he had to be able to fill in: bake bread, pastries and donuts, decorate cakes, drive the delivery truck. He also did all of the purchasing, planned the production and managed accounting, payroll and advertising. I believe his success was due to his versatility, work ethic, good humour and ability to motivate people to do their best. While I have a very different occupation, I believe that I learned a lot from my father that has helped me manage a research group."
