LEGO Engineering + Science

It’s always fun watching people push LEGO to the limits.  Here you can get a crash course in gear reduction and how to generate torque.  It’s interesting to see the differences in weights that can be lifted.  And it soon becomes apparent that the limitations aren’t in the gearing, or the motor, it’s the other materials which are failing.

Overlapping Clocks

This is a simple question, but sometimes, the simplest things are the most difficult to grasp.

Who would have thought that tying your shoes would be this interesting to watch, or more importantly, that there would be a different way to do it instead of the same way I’ve been doing it for 30ish years.

The Japanese are pretty crazy when it comes to their wood working joinery skills.  I remember reading somewhere that it’s all due to the lack of raw materials on the islands.  That meant that they couldn’t use nails, or forge large iron plates to connect timber together, instead they had to come up with these insane impossible looking joints.  It’s really beautiful, and satisfying to watch.  You should check it all out.

Cat Drawings

A Hilbert curve is one of those weird things in mathematics.  Does it have any use in real life, or is it just something to theorize about?  Well, this is the modern age, we have the technology to make complex Hilbert curves in real life.  This is also the internet, which is a series of tubes to send cat pictures to each other.

It’s only fitting that someone wrote code, and made a machine to draw a cat inside of a Hilbert Curve.

It’s a really boring video, honestly.

Prime Numbers

Prime Numbers are one of the the cool interesting things in math.  Lucas Numbers are something I’ve never heard about, but like all math proofs, it’s been proven and crazy over the years that it seems to work.  How exactly these patterns were discovered is another issue altogether.  Seriously, look how fast they increase, (at least at the Lucas-Lehmer sequence).  Come on, who thought of these patterns.  Who had the time?  Why’d they do it?  Crazy.

Analog Calculator

I think this is pretty damn impressive.  Mostly the mechanical engineering part.  There is some really detailed pieces of engineering in there, the milled brass parts, the recessed numbers, everything about this screams impressively well made.  Analog things like this are cool, I wish there were more of them around.


Round Pi

Apple Pi

Today is commonly called Pi day because when us Americans write it as shorthand you get 3.14.  Last year was the once in a century where if you timed it right you got a whole bunch of digits.  This year there’s nothing to time, it’s rounded to 3.1416.  That’s close enough to all you’ll ever need to know about pi.  Now enjoy the photo of Apple Pie above and continue about your merry day.

A Circle Plane?

Yes, you read that right, and your eyes aren’t lying to you, the people over at Flite Test have decided to make a circle plane, or tubular plane.  Basically, a plane with it’s wings arced up into each other to form a circle.  It looks ridiculously unstable, at first that is.

First the started small, and eventually scaled up.  When it’s flying, it’s pretty cool, and gigantic.  One of the games they played was flying smaller planes through the hoop.  It’s cool.  In a smaller test another plane got caught in the tail, but couldn’t manage to drag down the plane.  Eventually they had to hold it on a golf cart in order for it to take off.  It also looks pretty redundant, with a big chunk taken out of it’s circle it’s still flying very stable, but then again, it has a huge wing surface area, so it’s probably alright.

I think the coolest part though is watching the giant thing fly, and fly pretty slow with the quick nimble fighters flying all around, and through it.  Watching giant things fly real slow is cool.

Puzzle Blueprints

You’ve all seen these classic puzzles.  They have a objective, disassemble the locked rings, or make a shape using only 3 of the 4 pieces.  Well, have you ever wondered how they are made?  You’re in luck, William L. Hunter drew up some blueprints for a dozen or so of these different mind puzzles.  You can print them out and follow them to make your own puzzle, or just frame them yourself.

Take a look at the full imgur album to get some ideas.  It looks and sounds like these images came from this book: Wood-turning problems in blueprint form.  Sadly, Amazon doesn’t list it in stock, nor is another of William L. Hunter’s books available.
