Why this math professor is putting actors in classrooms
  + stars: | 2024-03-18 | by ( Leah Collins | ) edition.cnn.com   time to read: +3 min
Loh’s way of doing that is by creating Zoom classes that feel more like social media than traditional learning. Called live.poshenloh.com, the platform employs exceptionally talented US high school students to teach mathematics via livestream. Loh came up with the idea during the pandemic, when livestream learning became commonplace, but not necessarily engaging for students. “Most people had the experience that a Zoom math class was very effective at putting children to sleep,” he told CNN. “I didn’t realize that mathematics and the performing arts could harmonize together in such a wonderful way.”

CrowdStrike CEO George Kurtz told CNBC's Jim Cramer why the cybersecurity company is partnering with Nvidia , saying his company can offer more advanced and cost-effective services by making use of the semiconductor giant's artificial intelligence technology. "We've got the data, they've got the power and the software." Kurtz compared AI to an engine and data to oil, saying his company has data "in spades," collecting trillions of data signals and threat events per day. Cyber criminals are growing more capable, Kurtz stressed, saying they've democratized attacks for the "cyber crime masses." This means unskilled attackers are now able to access and use advanced technology even if they don't understand it, he said.

The “X-Men: Apocalypse” star, 43, wrote in an Instagram post Wednesday that she was diagnosed with breast cancer last year and would not have discovered it if her physician, Dr. Thaïs Aliabadi, had not calculated her breast cancer risk score. A breast cancer risk assessment tool uses a statistical model to estimate a woman’s risk of developing breast cancer over the next five years as well as over her lifetime, or up to about age 90, according to the National Cancer Institute. Two models are commonly used as breast cancer risk assessment tools: the Gail Model and the Tyrer-Cuzick Risk Assessment Calculator. An online version of the breast cancer risk assessment tool, using the Gail Model, is available for anyone to take at bcrisktool.cancer.gov. In fact, some women who do not develop breast cancer have higher risk estimates than some women who do develop breast cancer,” according to the National Cancer Institute’s website.

Key Takeaways From Super Tuesday
  + stars: | 2024-03-06 | by ( Susan Milligan | March | At A.M. | ) www.usnews.com   time to read: +3 min
Super Tuesday confirmed what Americans already knew: Barring a dramatic event, it's a two-person race now, with a November rematch between President Joe Biden and former President Donald Trump. Here are some takeaways:Both Trump and Biden Lost Support to Protest Voters. In Minnesota, the "uncommitted" got 19% of the vote, attributed to unhappiness over Biden's policy toward the Gaza war. Trump, meanwhile, lost Vermont to the now-departed-from-the-race Nikki Haley and lost sizable chunks of the GOP primary electorate to the former South Carolina governor. Democratic Rep. Adam Schiff had two Democratic colleagues, Rep. Katie Porter and Rep. Barbara Lee, vying with him for the top two lines.

Nikki Haley is said to be planning to drop out of the presidential race. Donald J. Trump rolled up victories across the country on Super Tuesday, and by the end of the evening it was clear that the former president had left Nikki Haley in the delegate dust. Ms. Haley plans to make it official on Wednesday morning, according to multiple people familiar with her plans, with an event where she will drop out but not immediately offer her endorsement to Mr. Trump. That is important because tucked inside Mr. Trump’s often dominant statewide victories on Tuesday were signs of vulnerability for the fall. He showed some of the same weakness in the swingy suburban areas that cost him the White House in 2020.

Trump won Alabama, Arkansas, California, Colorado, Massachusetts, Maine, Minnesota, North Carolina, Oklahoma, Tennessee, Texas and Virginia, with results from Alaska and Utah yet to come. “If Donald Trump returns to the White House, all of this progress is at risk. In Virginia, Haley got 35% of the GOP primary vote and posted similar numbers in Massachusetts. Haley had strong fundraising numbers in January and February, but it's possible the money will dry up after Trump's Super Tuesday wins.

Instead, they were trying to figure out if they could capitalize on the "positive thinking" trend.

Still, giving the models positive statements provided some surprising results.

When Nikki Haley summoned the national media to Greenville, S.C., on Tuesday, she did something that was strikingly unusual even in this most bizarre of campaigns. She devoted an entire speech to explaining why she was not dropping out of the presidential race. Hungry for attention, and fed up with fielding questions about why she wasn’t reading the room and the polls, her team had billed the event, tantalizingly, as a “State of the Race” speech. “Some of you — perhaps a few of you in the media — came here today to see if I’m dropping out of the race,” Ms. Haley said. Ms. Haley was enjoying herself, finally able to say what she has long thought about Mr. Trump and seemingly delighted that she had focused national attention on her message.

LOS ANGELES (AP) — Thousands of fans watching Tiger Woods in his 2024 debut missed out on the best golf Thursday at the Genesis Invitational. In the group ahead of Woods was Patrick Cantlay, looking as though he wants to be the next Southern California native to win at Riviera. Cantlay opened with three birdies in four holes and never really slowed until a sycamore tree halted his great run. “Jordan and I were a bunch under on the front nine and a day where I putted really, really well. That shank was a shocker, and perhaps more concerning was Woods saying his back was acting up int the final hour, leading to the shank.

The racial wage gap may be shrinking, but it's still got a ways to go. The median weekly earnings for full-time wage and salaried Black or African American 16-to-24-year-olds was $614. Though a smaller gap than the national one, that still works out to be about 82 cents to white workers' dollar. Children born in higher income and higher wealth families will have greater access to opportunities.

Even in a campaign in which Mr. Trump’s dominance has sapped the race of much of its drama, his win in Nevada felt particularly preordained. Embarrassingly for Ms. Haley, she was heavily outvoted in that election by a “None of These Candidates” option on the ballot. She was essentially unopposed, but even without Mr. Trump on the ballot, Republican voters rejected her. Ms. Haley still won the contest, but its results were effectively immaterial. Mr. McDonald also repeatedly pushed false claims of voter fraud that remain at the heart of Mr. Trump’s lie that the 2020 election was stolen from him.

I arrived by means of mathematics, specifically simple mathematics — algebra, geometry and calculus, the kind of mathematics that adolescents do. I am only a mathematical tourist, but my experience has led me to believe that mathematics is rife with intimations of a divine presence. For many mathematicians, there is no question that God is somehow involved. Newton, for example, believed that mathematics exemplified thoughts in the mind of God. The first is the question of whether mathematics is created or discovered.

Generative AI Neural networks are the heart of the increasingly popular type of AI known as generative artificial intelligence , or gen AI for short. Both traditional AI and gen AI systems rely on data and can be used to automate decision-making tasks. Microsoft's AI virtual assistant Copilot — which went live in November — is perhaps the most prominent generative AI feature among our portfolio companies. Bias Bias is another downside to AI systems — and LLMs in particular — that users need to consider. While GPUs have the upper hand in AI training, CPUs are understood to perform AI inference well.

HELSINKI (AP) — Ex-Prime Minister Alexander Stubb was projected to win the first round of Finland's presidential election on Sunday and face runner-up Pekka Haavisto in a runoff next month. Finnish public broadcaster YLE projected that Stubb won the first round of the presidential election with 27.3% of the votes, while Haavisto, an ex-foreign minister, took second place with 25.8%. Recent polls suggest that former Prime Minister Alexander Stubb, 55, and ex-Foreign Minister Pekka Haavisto, 65, are the leading contenders. The president also acts as the supreme commander of the Finnish military, a particularly important duty in Europe's current security environment. About 4.5 million citizens were eligible to vote for Finland’s new head of state from an array of nine candidates — six men and three women.

Last year, this natural spectacle coincided with the woolly propagation of two new colonies of the Crochet Coral Reef, a long-running craft-science collaborative artwork now inhabiting the Schlossmuseum in Linz, Austria, and the Carnegie Museum of Art in Pittsburgh. The project also explores mathematical themes, since many living reef organisms biologically approximate the quirky curvature of hyperbolic geometry. By contrast, the surface of a sphere displays constant positive curvature; at all points, the surface bends inward toward itself. And a hyperbolic plane exhibits constant negative curvature; at all points, the surface curves away from itself. Reef life thrives on hyperbolism, so to speak; the curvy surface structure of coral maximizes nutrient intake, and nudibranchs propel through water with frilly flanges.

Erno Rubik, inventor of the Rubik's Cube, holds one of the cubes at the International Toy Fair in Nuremberg, Germany, Jan. 29, 2020. It took a month of twisting and turning for the first person to solve a Rubik's Cube. That person was Erno Rubik, now 79, the iconic puzzle toy's creator. A source of pride, envy and frustration, the Rubik's Cube turns 50 this year and, under the ownership of Spin Master, it shows no signs of retirement. "Rubik's isn't just a toy," said Sam Susz, senior director of global marketing at Spin Master.

The latest calculations from several science agencies showing Earth obliterated global heat records last year may seem scary. Former NASA climate scientist James Hansen, often considered the godfather of global warming science, theorized last year that warming was accelerating. That’s 0.27 degrees (0.15 degrees Celsius) warmer than the previous record set in 2016 and 2.43 degrees (1.35 degrees Celsius) warmer than pre-industrial temperatures. NASA and the United Kingdom Meteorological Office had the warming since the mid-19th century a bit higher at 2.5 degrees (1.39 degrees Celsius) and 2.63 degrees (1.46 degrees Celsius) respectively. It’s the third time in the last eight years that a global heat record was set.

The analyst community (which forecasts individual stock earnings and prices) is also making estimates for 2024. Unfortunately, like their macroeconomic strategist brethren, Wall Street analysts also have a long history of being wrong on their forecasts. Since the S & P 500 rises in almost three out of four years, analysts are understandably a generally bullish group. There have been four years in the last 20 where the analyst estimates at the start of the year differed from the final estimates by a margin greater than 25%. No wonder the S & P 500 closed Friday at a new high for the year.
