The Old Calculator Web Museum

Original image

Remember that old paper-tape calculator your folks used to do their taxes? Or the crazy beige 70's calculator your high school math teacher insisted on using? Well, those look positively modern compared to what you'll find at The Old Calculator Web Museum, an extensive collection of vintage math machines.

The calculators in this online collection range from simply antiquated to utterly bizarre. Others look like they're taken from early NASA programs (surprise -- the Wang LOCI-2 was indeed used to test space suits at NASA). Some of the calculators have cool styling, like the Facit 1111, which shows its numbers in a hip, tilted typeface.

The museum also features an Advertising and Documentation Archive, which is a hoot. The ad for a Mathatronics Mathatron 8-48 calculator read thus (emphasis added):

"They laughed when I sat down to play the Mathatron."

"Little did they realize then that this was no ordinary $5,000 Mathatron. All they could see was the simple algebraic keyboard, and the paper tape readout.

"But underneath the Mathatron, cleverly disguised in the table, was capacity bringing the totals to 48 individually addressable storage registers, 480 steps of program memory, 18 prewired programs of 48 steps each, increased speed, and added program control!

"By my right hand, unknown to those snickering on my left, close by the candelabra, was an additional control box which told me, by blinking lights, which of the 10 loops I was addressing. And there were other buttons there, too.

"When I finished my evaluation of the formula involving trigonometric, logarithmic and other functions, matrix manipulations, triangulation and the solution of polynomials, they applauded generously." Send for complete details.

Other notable calculators: Hewlett Packard HP-01 Calculator Wristwatch (the gold version went for $795), Wang Model 360SE Calculator System (which featured high-end math functions at a low price -- as well as awesome Nixie Tube displays), and Toshiba BC-1211S Electronic Calculator (which omitted the division function to save money).

Check out the museum to satisfy your retro calculator fetish.

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.
