Children May Instinctively Know How To Do Division Even Before Hitting the Books, Study Finds
Published on February 26, 2022 at 02:55AM
An anonymous reader shares a report: We often think of multiplication and division as calculations that need to be taught in school. But a large body of research suggests that, even before children begin formal education, they possess intuitive arithmetic abilities. A new study published in Frontiers in Human Neuroscience argues that this ability to do approximate calculations even extends to that most dreaded basic math problem -- true division -- with implications for how students are taught mathematical concepts in the future. The foundation for the study is the approximate number system (ANS), a well-established theory that says people (and even nonhuman primates) from an early age have an intuitive ability to compare and estimate large sets of objects without relying upon language or symbols. For instance, under this non-symbolic system, a child can recognize that a group of 20 dots is bigger than a group of four dots, even when the four dots take up more space on a page. The ability to make finer approximations -- say, 20 dots versus 17 dots -- improves into adulthood.

Slashdot: AT&T Says Leaked Data of 70 Million People Is Not From Its Systems

AT&T Says Leaked Data of 70 Million People Is Not From Its Systems Published on March 20, 2024 at 02:15AM An anonymous reader quotes a report from BleepingComputer: AT&T says a massive trove of data impacting 71 million people did not originate from its systems after a hacker leaked it on a cybercrime forum and claimed it was stolen in a 2021 breach of the company. While BleepingComputer has not been able to confirm the legitimacy of all the data in the database, we have confirmed some of the entries are accurate, including those whose data is not publicly accessible for scraping. The data is from an alleged 2021 AT&T data breach that a threat actor known as ShinyHunters attempted to sell on the RaidForums data theft forum for a starting price of $200,000 and incremental offers of $30,000. The hacker stated they would sell it immediately for $1 million. AT&T told BleepingComputer then that the data did not originate from them and that its systems were not breached. &q

H&R Block, Meta, and Google Slapped With RICO Suit, Allegedly Schemed to Scrape Taxpayer Data Published on October 02, 2023 at 03:14AM Anyone who has used H&R Block's tax return preparation services since 2015 "may have unintentionally helped line Meta and Google's pocket," reports Gizmodo: That's according to a new class action lawsuit which alleges the three companies "jointly schemed" to install trackers on the H&R Block site to scan and transmit tax data back to the tech companies which then used elements of the data to engage in targeted advertising. Attorneys bringing the case forward claim the three companies' conduct amounts to a "pattern of racketeering activity" covered under the Racketeer Influenced and Corrupt Organizations Act (RICO), a tool typically reserved for organized crime.
