Ballot Measures Passed To Protect Abortion Rights | New Largest Prime Number

Abortion was on the ballot in 10 states, and seven of them passed constitutional amendments defending abortion rights. Also, this ginormous number has a whopping 41,024,320 digits, which isn’t very helpful for mathematicians but is certainly exciting for math nerds.

Seven States Passed Ballot Measures To Protect Abortion Rights

This week, science was on the ballot in many states. Voters across the country weighed in on issues like drug legalization, money to fund climate programs, and, of course, abortion rights. Ten states voted on the issue, and in seven of them, voters chose to protect or expand abortion rights. Those states are Maryland, Montana, Nevada, New York, Colorado, Arizona, and Missouri. On the flip side, voters in Florida, Nebraska, and South Dakota rejected measures that would protect abortion rights.

Ira Flatow talks with Tim Revell, executive editor at New Scientist, about the outcome of some sciencey ballot measures and what we can expect going into another Trump presidency. They also discuss the launch of the world’s first wooden satellite, what scientists learned when they put vampire bats on a treadmill, and more.

Math Enthusiast Finds The Largest Known Prime Number

Let’s go back to grade school—do you remember learning about prime numbers? They’re numbers that can only be divided by themselves and one.

So 2, 3, 5, 7, 11, and so on are prime numbers. The number 12, for example, wouldn’t be prime because you can divide it by other numbers, like 2 and 3. And as you count up and up, prime numbers become more sparse.

Math lovers are always competing to find the largest prime number, and just recently, an engineer discovered the largest one—so far. And you won’t believe how ginormous it is: It has more than 41 million digits.

Ira talks with Jack Murtagh, math writer and columnist for Scientific American, about why prime numbers are so cool, and the quest to find the largest one.
