In her boldest move, Goddard put her full name at the bottom of all the copies of the Declaration that her printing presses churned out and distributed to the colonies. It was the first copy young America would see that included the original signers’ names — and Congress commissioned her for the important job.
In 2010, programmers found that a 3x3x3 Rubik’s cube can be solved in a maximum of 20 moves from any starting position, no matter how scrambled.
A year later, Demaine, Eisenstat and their colleagues devised a formula to solve a Rubik’s cube with sides of any length and found that the number of moves required for a cube of side n is proportional to n2/log n.
Finding the number for a cube with n=3 took several years of computing time and Demaine estimates that the n=4 case would take billions of times longer. “I conjecture it will never be fully solved,” he says.
This is the upper limit for the most scrambled cubes, but many cubes will not take that long. Figuring out whether any given configuration of a cube will take fewer moves is tricky. “We know an algorithm to solve all cubes in a reasonable amount of time,” Demaine says. “But if I give you a particular configuration of the cube, and then you want to solve it with the fewest moves for that configuration, that’s really tough.”
The number of violent attacks on U.S. soil inspired by far-right ideology has spiked since the beginning of this century, rising from a yearly avarage of 70 attacks in the 1990s to a yearly avarage of more than 300 since 2001. These incidents have grown even more common since President Donald Trump’s election.
The Southern Poverty Law Center, a nonprofit that researches U.S. extremism, reported 900 bias-related incidents against minorities in the first 10 days after Trump’s election – compared to several dozen in a normal week – and the group found that many of the harassers invoked the then-president-elect’s name. Similarly, the Anti-Defamation League, a nonprofit that tracks anti-Semitism, recorded an 86 percent rise in anti-Semitic incidents in the first three months of 2017.
Four years later, Slepian was murdered at his home. The total count between 1978 and 2015, writes Haugeberg, was eleven murders (nine of them physicians), twenty-six attempted murders, 185 arsons, forty-two bombings, and 1,534 vandalizations of clinics.
Why Are Bird Eggs Egg-Shaped? An Eggsplainer: A new study points to a surprising reason for the varied shape of bird eggs—and shows that most eggs aren’t actually egg-shaped. Egg-scuse me? by Ed Yong. pdf
