Minimal Boolean Formulas Posted on Wednesday, May 18, 2011. 28. That's the minimum number of AND or OR operators you need in order to write any Boolean function of five variables. Alex Healy and I computed that in April 2010. Until then, I believe no one had ever known that little fact. This post describes how we computed it and how we almost got scooped by Knuth's Volume 4A which considers the problem for AND, OR, and XOR.

How Prehistoric Mammoth Tusks Could Help Bust Modern-Day Ivory Smugglers

gizmodo.com Margherita Bassi 2026-03-05 17:00:57

Selling elephant ivory—a hard white material from elephant tusks, for which elephants are often killed—is illegal. Selling ivory collected from the remains of extinct Mammoths, however, is—somehow—not. Because the two are hard to tell apart, illegal traders are slipping under the radar by mixing elephant ivory with legally traded mammoth ivory. A new forensic tool, however, might soon put an end to this nefarious trick. Wildlife forensic scientists in China suggest that authorities can differen

Even if you enjoy cooking, waiting for a pot of water to boil is probably one of the things you'd rather not have to deal with. And yes, the more you watch it, the slower it boils -- that's just science. But did you know that some ways of heating a pot are quicker than others? They can be better for other reasons, too. Using an electric stove can take longer than you'd like, making a gas range the preferred choice -- not to mention they usually heat your pots and pans more evenly, too. And with

Bacteria can be used to turn plastic waste into painkillers, researchers have found, opening up the possibility of a more sustainable process for producing the drugs. Chemists have discovered E coli can be used to create paracetamol, also known as acetaminophen, from a material produced in the laboratory from plastic bottles. “People don’t realise that paracetamol comes from oil currently,” said Prof Stephen Wallace, the lead author of the research from the University of Edinburgh. “What this
