Sequence of the Day [talk] Sequence of the Day for April 28 A181284: Decimal expansion of 2√   9 121  100 30  −  1208 121   . 2727272727...272727272727.272727...2727089696969... (The first ellipsis omits four instances, out of fifteen, of the digit pairs 27, the second omits nine, out of fourteen.) This is an example of a so-called zebra irrational number. Most irrational numbers in the OEIS are small and in the unit interval (between 0 and 1). This is one is an interesting exception to that trend.

Today in Math History [talk] Today in Math History for April 28 April 28, 1664 Sir Isaac Newton is elected a scholar at Trinity College Cambridge. April 28, 1835 Eugène Charles Catalan marries Charlotte Perin. April 28, 1903 Josiah Willard Gibbs dies in New Haven, Connecticut. April 28, 1906 Kurt Gödel is born in Brünn (now Brno). April 28, 1933 Edmund Landau is relieved from having to teach his summer course due to the Nazi policy of removing Jewish professors. It remains unclear at this point whether the accident would have been prevented if existing measures had been enforced. The incident was in some ways different from what the legislators intended to prevent when many of these measures were signed into law twenty years ago. A subcommittee has been appointed to review possible unintended consequences of tougher measures. Since the classifying authority also classified the reason the requested information was classified in the first place, the judge had no choice but to dismiss all charges, though without prejudice. The prosecutor, however, remains convinced that other evidence will soon come to light which will enable her to refile all charges. The filibuster was averted at the last minute when a small group of legislators decided to ignore their party's position on the issue and side with the majority. The vote was nevertheless very close and mostly along party lines. The president has not given any indication on whether he will sign or veto the bill now that those provisions he declared most important at the outset have been significantly weakened.

After much deliberation, the panel decided to postpone further discussion of the issue until more information becomes available. In the meantime, the investigation will proceed, but at a lower priority level. The panel also recommended that the chain of custody be strictly observed and documented until further notice.

“I don't know what I would have done if that had been the case,” John Smith said at the press conference convened earlier today. “At the time, I was operating under the assumption that all the prototypes were back in hangar,” he explained. Later on it was learned that one of the prototypes was still unaccounted for, though it was retrieved prior to the press conference.

General consensus has it that the subcommittee's meeting with the provost was designed not so much to change his mind as to delineate which points were open to concession and which were not. With both parties to the dispute digging in their heels, it appears that a resolution of the disagreement is not forthcoming at any point in the near future.
