Richard P. Feynman to Frederich Hipp, April 5, 1961

Editor's Note: Frederich Hipp, a high school student, was fascinated by physics ("atomic theory and quantum mechanics in particular") and had built a cloud chamber for his science project. He was concerned, however, that he had little aptitude for math. His question to Feynman: "Can a person of normal mathematical ability master enough math to do work on some professional level in this field?" Mr. Frederich Hipp New Milford, Connecticut Dear Sir: To do any important work in physics a very good mathematical ability and aptitude are required. Some work in applications can be done without this, but it will not be very inspired. If you must satisfy your "personal curiosity concerning the mysteries of nature" what will happen if these mysteries turn out to be laws expressed in mathematical terms (as they do turn out to be)? You cannot understand the physical world in any deep or satisfying way without using mathematical reasoning with facility. How do you know you don't have an aptitude for math? Perhaps you disliked your teacher, or it was presented wrong for your type of mind. What do I advise? Forget it all. Don't be afraid. Do what you get the greatest pleasure from. Is it to build a cloud chamber? Then go on doing things like that. Develop your talents wherever they may lead. Damn the torpedoes—full speed ahead! What about the math? Maybe (1) you might find it interesting later when you need it to design a new apparatus, or (2) you may not go on with your present ambition to understand everything, but instead find yourself a leader in some other direction, such as building the most ingenious rocket-ship control devices, or (3) biological problems may ultimately absorb all your interest and talent for doing experiments and learning about nature, etc. If you have any talent, or any occupation that delights you, do it, and do it to the hilt. Don't ask why, or what difficulties you may get into. If you are an average student in everything and no intellectual pursuit gives you real delight, then I don't know how to advise you. You will have to discuss it with someone else. It is a problem that I have not thought about very hard. Sincerely, R. P. Feynman

France celebrates virus heroes on redesigned Bastille Day

Added: 14.07.2020 10:03 | 22 views | 0 comments

France is recalibrating Bastille Day’s usual grandiose military parade to celebrate heroes of the coronavirus pandemic instead. Ambulance drivers, supermarket cashiers, postal workers as well as frontline medics who died fighting Covid-19 are all being honoured on the country’s biggest national holiday. This year’s commemorations will also pay homage to former president Charles de Gaulle, eight decades after the historic appeal he made to opponents of France’s Nazi occupiers which gave birth to the French Resistance. But the battle against the virus, which has claimed more than 30,000 lives in France, is expected to be the main focus of the...

A commonly expressed protein in skin -- periostin -- can directly activate itch-associated neurons in the skin, according to new research. Blocking periostin receptors on these neurons reduced the itch response in a mouse model of atopic dermatitis, or eczema.
