Congrats! Now, does this mean that when you run BrickBash, you aren’t allowed
to keep any of the gate proceeds? I mean, seriously, what does happen to all
the monies we fork over for admission? I propose that you start divying it up
amongst displaying attendees.
Hopefully by the time BB rolls around again you’ll have forgotten all about this
and won’t remember to make good on your threat. ;P

This will open doors for us in areas such as facility usage, grants,
partnership with museums and educational institutions, donations, fund
raising, and more.
Bricks for Brains is an organization through which I do educational work
with LEGO. We have formed our board, achieved 501c3 tax-exempt status, and
now we move on to designing and implementing more hands-on exhibits and
other educational services and products.
We are quite excited!

Congradulations, that’s very cool. Now is your Bricks for Brains and this
Bricks for Brains the same?

Thanks!
No that’s somebody else. I had hoped he would stop using it after I brought it
to his attention last year.

Lego Bible Study went well. Though folks were very eager to learn more about
our construction clubs, I managed to keep us focused on the textual
deconstruction at hand. Unfortunately, a young person showed up, so I couldn’t
spend as much time on the bawdy stuff as I would have wanted. Oh, well. If we
had everything, where would we put it? And how long would it take to sort it
all?
I threw together a Moses amongst the bullrushes play set:
and a Jesus of Nazareth minifig:
He rode along in my nametag all Easter morning.
Happy Easter, all!

Yeah, about 5 minutes after I submitted that I realized just how stupid I've
become as of late (I plead mercy due to a very nasty sinus infection... but dang
it, I should have caught that even if I was unconcious). What will make it even
funnier (for you) is that I'm a physicist by training, so it's not like I don't
know this stuff. Groan...

A 12-12-17 triangle is very nearly right, and has angles of about 44.9 degrees.
I used four of them in making a stop sign:
Note that all eight corners are nicely studded down.

And now a teachable moment! You’ve made my week! As DaveE alludes elsewhere in
this thread, a 3-4-5 triangle has angles of about 36.87, 53.13, and 90 degrees.
Making one of these triangles is a great way to build a strong right angle. A
triangle with angles of 30, 60, and 90 degrees is a different animal: half an
equilateral triangle. It can help in making a regular hexagon. Unfortunately,
at least one of its sides must have a funny (irrational) length, so it isn’t the
easiest thing to build in brick or technic.

p.s. I must admit that when I first read Brian’s statement, I made a noise so
horrible my colleagues here in the math department wondered if I was ill. Don’t
worry. I’ll be fine. Eventually.

Last spring, my colleagues got funding for two shiny display cabinets for my
math department. Appropriate displays were just slow enough in coming that I
could (quickly) haul out several of my Lego math demonstration models and fill
an entire case with them:
Home Plate
This familiar-looking shape does not actually exist. Look at the triangle on
the bottom. (Use the dashed black line as its long side.) The side lengths of
12, 12, and 17 do not obey the Pythagorean Theorem—check 12^2+12^2 and 17^2.
However, it’s very, very nearly a right triangle, so we let it slide.
Turned Squares
Here are two squares. Look at the larger one. If you include the white dotted
lines, you can see that the larger square is made up of four right triangles
whose sides are very, very close to 12-12-17. These numbers were obtained using
a continued fraction.
The smaller square is made up of four 6-8-10 right triangles and one 2 by 2
square. The yellow and blue triangles are illustrated with dotted lines. Of
the five polygons in the display, this is the only one whose linear measurements
are all integers.
Equilateral Triangles
Here are two equilateral triangles. The triangle with sides of length 9 does
not work well in Lego. Its altitude is about 7.794—not an integer value—so its
top vertex (where yellow and red meet) is not near a grid point, so it cannot
connect to the gray baseplate.
The triangle with sides of length 15 does work well. Its altitude is about
12.99—very close to 13—so its top vertex (where blue and yellow meet) connects
solidly to the gray baseplate.
Blue Wave
This wavy object is generated by the function z=5cos(x^2+y^2)+6. In Calculus
II, we learn how to find the size of one slice; in Calculus III we learn how to
slice up the entire object and find its volume.
Attention: Dr. Masi, Dr. Masi to the fourth floor.
