2,053 Nuclear Explosions in One Video

Original image

Artist Isao Hashimoto created an animation showing every nuclear test between 1945 (the first Manhattan Project test, called Trinity) and 1998 (a test in Pakistan). The total number? 2,053, according to the Stockholm International Peace Research Institute. Note that this number doesn't include the rumored North Korean tests in 2006 and 2009. While the video starts slowly, by the late 1950s things are getting intense. Testing peaks in 1962, when over a hundred blasts are shown. You can follow the running tally at the top of the screen to see who's testing, when, and where. After twelve minutes, the video goes silent and runs through the tests by country of origin, so you can see who's blowing up what, where.

Hashimoto said (emphasis added): "This piece of work is a bird's eye view of the history by scaling down a month length of time into one second. No letter is used for equal messaging to all viewers without language barrier. The blinking light, sound and the numbers on the world map show when, where and how many experiments each country have conducted. I created this work for the means of an interface to the people who are yet to know of the extremely grave, but present problem of the world."

And here's video of Trinity, the test on July 16, 1945 which prompted Robert Oppenheimer to quote the Bhagavad Gita: "Now I am become Death, the destroyer of worlds."

And here's a photo of Trinity. According to Wikipedia:

The Trinity explosion, 16 milliseconds after detonation. The fireball is about 600 feet (200 m) wide. The black specks silhouetted along the horizon are trees.

These $425 Jeans Can Turn Into Jorts

Opening Ceremony

Modular clothing used to consist of something simple, like a reversible jacket. Today, it’s a $425 pair of detachable jeans.

Apparel retailer Opening Ceremony recently debuted a pair of “2 in 1 Y/Project” trousers that look fairly peculiar. The legs are held to the crotch by a pair of loops, creating a disjointed C-3PO effect. Undo the loops and you can now remove the legs entirely, leaving a pair of jean shorts in their wake. The result goes from this:

To this:

The company also offers a slightly different cut with button tabs in black for $460. If these aren’t audacious enough for you, the Y/Project line includes jumpsuits with removable legs and garter-equipped jeans.

This First-Grade Math Problem Is Stumping the Internet
May 17, 2017

If you’ve ever fantasized about how much easier life would be if you could go back to elementary school, this math problem may give you second thoughts. The question first appeared on a web forum, Mashable reports, and after recently resurfacing, it’s been perplexing adults across social media.

According to the original poster AlmondShell, the bonus question was given to primary one, or first grade students, in Singapore. It instructs readers to “study the number pattern” and “fill in the missing numbers.” The puzzle, which comprises five numbers and four empty circles waiting to be filled in, comes with no further explanation.

Some forum members commented with their best guesses, while others expressed disbelief that this was a question on a kid’s exam. Commenter karrotguy illustrates one possible answer: Instead of looking for complex math equations, they saw that the figure in the middle circle (three) equals the amount of double-digit numbers in the surrounding quadrants (18, 10, 12). They filled out the puzzle accordingly.

A similar problem can be found on the blog of math enthusiast G.R. Burgin. His solution, which uses simple algebra, gets a little more complicated.

The math tests given to 6- and 7-year-olds in other parts of the world aren’t much easier. If your brain isn’t too worn out after the last one, check out this maddening problem involving trains assigned to students in the UK.
