Mathematician Akshay Venkatesh: Jack of all fields, master of one

Akshay Venkatesh

Mathematics is a young person’s game. There is speculation that the brain’s neural pathways become less plastic over time, limiting the insights of older people. Whatever the reason, the most path-breaking work in maths and physics (which is essentially applied maths), has been done by people under 40. The discipline is studded with prodigies. But even by mathematical standards, Akshay Venkatesh is unusually prodigious. The newly minted Fields medallist emigrated from Delhi to Perth at the age of two, or rather, his parents did. He joined the bachelor’s course in mathematics at the University of Western Australia when he was 13. By then, he had already won several medals at Maths Olympiads. Venkatesh graduated at 16 and completed his PhD from Princeton University at 20. After holding a post-doctorial position at MIT, he was a Clay Research Follow at the Clay Mathematics Institute. The 36-year-old is currently a professor at Stanford, and intends to transfer to the Institute of Advanced Studies at Princeton in a few months. The Australian citizen has won a multitude of awards, including The Infosys Prize, The Ramanujam Prize, and the Ostrowski. But the Fields Medal is considered the equivalent of the Nobel in terms of prestige for pure mathematicians, even though it carries only a nominal cash award of CAD$15,000. The prize was created by Canadian mathematician John Charles Fields in 1936 and is handed out only to mathematicians under 40.

Bitcoin losing lustre as underworld switches over to other currencies

Bitcoin

Bitcoin is losing its lustre with some of its earliest and most avid fans -- criminals -- giving rise to a new breed of virtual currency.

Privacy coins such as monero, designed to avoid tracking, have climbed faster over the past two months as law enforcers adopt software tools to monitor people using bitcoin. A slew of analytic firms such as Chainalysis are getting better at flagging digital hoards linked to crime or money laundering, alerting exchanges and preventing conversion into traditional cash.

The European Union’s law-enforcement agency, Europol, raised alarms three months ago, writing in a report that “other cryptocurrencies such as monero, ethereum and Zcash are gaining popularity within the digital underground.” Online extortionists, who use ransomware to lock victims’ computers until they fork over a payment, have begun demanding those currencies instead. On Dec. 18 hackers attacked up to 190,000 WordPress sites per hour to get them to produce monero, according to security company Wordfence.

For ransomware attacks, monero is now “one of the favorites, if not the favorite,” Matt Suiche, founder of Dubai-based security firm Comae Technologies, said in a phone interview.

Monero quadrupled in value to $349 in the final two months of 2017, according to coinmarketcap.com, placing it among a number of upstart coins that that rose faster than bitcoin, the world’s most valuable digital currency. Bitcoin roughly doubled in the same period, data compiled by Bloomberg show.
