Zeroing In on Catalan’s Conjecture
Fermat’s last theorem is just one of many examples of innocent-looking problems that can long stymie even the most astute mathematicians. It took about 350 years to prove Fermat’s scribbled conjecture, for instance. Now, Preda Mihailescu of the Swiss Federal Institute of Technology in Zurich has proved a theorem that is likely to lead to […]

Scrabble’s Random Letters
In the popular SCRABBLE Brand Crossword Game, players create words from letters selected at random from a stockpile of 100 tiles. The tiles are laid down on a board 15 squares high by 15 squares wide to form an interlocking, crossword arrangement. Each letter of the alphabet has a particular value and the number of […]

Conquering Catalan’s Conjecture
Innocent-looking problems involving whole numbers can stymie even the most astute mathematicians. As in the case of Fermats last theorem, centuries of effort may go into proving such tantalizing, deceptively simple conjectures in number theory. Now, Preda Mihailescu of the University of Paderborn in Germany finally may have the key to a venerable problem known […]

What your earwax says about your ancestry
Both armpit and ear wax secretions are smellier in Caucasians than in Asians, thanks to a tiny genetic change that differs across ethnic groups.

Hiding up your nose is a clever strategy for ticks
Found hiding in the noses of Ugandan chimps, a new tick species hitchhiked its way to America in a researcher's nose.

THE SUN’S NEW TRANS-NEPTUNIAN PLANET The Lowell Observatory has made the discovery of a celestial body whose rate of motion and path among the stars indicate that it is a new member of the sun’s family of planets out beyond Neptune. Twenty-five years ago, Dr. Percival Lowell, director and founder of the Observatory at Flagstaff, […]

TRAVEL TO THE MOON BY THE YEAR 2050 By the year 2050, Earth-dwellers will probably be able to travel to the moon and to communicate with their terrestrial home by telephoning over a beam of light. They will get there by traveling in a rocket ship at a speed of some 50,000 miles an hour, […]
