UC Davis mathematician Dan Romik has extended this problem to a hallway with two turns, and shows that a 'bikini top' shaped sofa is the largest so far found that can move down such a hallway.<br /><br />Click <a href="https://phys.org/news/2017-03-sofa-problem-stumped-mathematicians-furniture.html">here</a> for more information.Bassam Abdul-Bakihttps://plus.google.com/105978943918433648626noreply@blogger.com0tag:blogger.com,1999:blog-14844134.post-88257562810801642172017-03-26T16:05:00.000-04:002017-03-26T16:05:29.508-04:00French Mathematician Yves Meyer Wins Top Prize for 'Wavelet Theory'A French mathematician known for his pioneering work on a theory used for applications ranging from image compression to the detection of gravitational waves from the merging of black holes has earned one of the world's top prizes in mathematics.<br /><br />Yves Meyer, a professor emeritus in mathematics at the École normale supérieure Paris-Saclay in France, will receive the Abel Prize, the Norwegian Academy of Sciences and Letters (which awards the prize) announced today (March 21) in Oslo. The prize, which comes with a cash award of 6 million Norwegian krone ($710,000), will be bestowed by King Harald V of Norway on May 23.<br /><br />Meyer was honored largely "for his pivotal role in the development of the mathematical theory of wavelets," the academy said. His work on wavelets began in the mid-1980s.<br /><br />Click <a href="http://www.space.com/36163-mathematician-yves-meyer-wins-abel-prize.html">here</a> for more information.Bassam Abdul-Bakihttps://plus.google.com/105978943918433648626noreply@blogger.com0tag:blogger.com,1999:blog-14844134.post-58236338512207492092017-01-19T09:40:00.000-05:002017-01-19T09:40:56.785-05:00If the Moon Were Only 1 PixelA tediously accurate <a href="http://joshworth.com/dev/pixelspace/pixelspace_solarsystem.html">map of the solar system</a>.Bassam Abdul-Bakihttps://plus.google.com/105978943918433648626noreply@blogger.com0tag:blogger.com,1999:blog-14844134.post-74582134768392569882016-07-30T11:11:00.000-04:002017-01-07T16:44:24.511-05:00CalcaI found this little gem of a tool called <a href="http://calca.io/">Calca</a>.

The latest number-crunching champ isn't a supercomputer--it's a hacked-together PC.
<br/><br/>
Shigeru Kondo of Iida, Nagano Prefecture, worked with software designed by Northwestern University grad student Alexander Yee, and followed up their 2010 feat of reckoning pi to 5 trillion digits.
<br/><br/>
The result was achieved earlier this month after 371 days of computation and numerous hard drive failures.
