It's Full of Stars: Akin’s Laws of Spacecraft Design Engineering is done with numbers....

Akin’s Laws of Spacecraft Design

  1. Engineering is done with numbers. Analysis without numbers is only an opinion.
  2. To design a spacecraft right takes an infinite amount of effort. This is why it’s a good idea to design them to operate when some things are wrong.
  3. Design is an iterative process….

crookedindifference: The ‘Original’ Inventor of Algebra Abū ʿAbdallāh Muḥammad ibn Mūsā al-Khwārizmī, earlier transliterated as Algoritmi or Algaurizin, (c. 780, Khwārizm – c. 850) was a Persian mathematician, astronomer and geographer, a scholar in the House of Wisdom in Baghdad. In the twelfth century, Latin translations of his work on the Indian numerals introduced the decimal positional number system to the Western world. His Compendious Book on Calculation by Completion and Balancing presented the first systematic solution of linear and quadratic equations in Arabic. In Renaissance Europe, he was considered the original inventor of algebra, although we now know that his work is based on older Indian or Greek sources. He revised Ptolemy’s Geography (systematized and corrected Ptolemy’s data for Africa and the Middle east) and wrote on astronomy and astrology. Some words reflect the importance of al-Khwarizmi’s contributions to mathematics. “Algebra” is derived from al-jabr, one of the two operations he used to solve quadratic equations. Algorism and algorithm stem from Algoritmi, the Latin form of his name. His name is also the origin of (Spanish) guarismo and of (Portuguese) algarismo, both meaning digit.

Misconceptions about the Golden Ratio

cab1729:

why everything you think you know about applications of this number is wrong

(via @pickover)

Excellent and very clear! Relevant, now that TV series “Touch” is using references to Golden Ratio.

theatlantic: Ladies and Gentlemen, E=MC2 and Other Einstein Archive Treasures The joy of the Internet, friends. Earlier today the Hebrew University of Jerusalem and the California Institute of Technology unveiled a new online repository of 2,000 high-resolution scans from their collected manuscripts of Albert Einstein. Among them, the scribble above — one of three existing examples in Einstein’s own handwriting. Read more. [Image: Einstein Archives Online]
