The ceiling of these bathrooms in Topkapi, designed by the great Mimar Sinan, have these beehive holes which allow the rooms to be very bright without having windows. It’s such brilliant architectural solution!
@ColinTheMathmo@tintenliebe No. you’re absolutely correct. Most Geometry course cover sine, cosine, and tangent using right triangles. And then the Unit Circle isn’t introduced until one or two more years later, in either Algebra 2 or Precalculus. Drives me crazy. I would much rather students experience the trig ratios the first time with the unit circle.
Geometry is usually in 9th grade (13/14 yo), but accelerated students can see it in 8th at 12/13 years old. #mtbos#geometry#MathEd#ClassroomMath
A #RosettaCode contribution for #ATS -- the old insideness of a convex hull algorithm. I decided to do this because I am likely to stick the algorithm within my next Bézier intersection algorithm (which will be coded in Ada using homogeneous geometric algebra, not in ATS using euclidean, but whatever) --
Hey #gamedev#physics people ( #math and #geometry too I guess?) , I'm playing with writing some basic collision detection code. So far just intersection and sweep tests for AABBs and Spheres (realtimerendering's matrix of shape intersections is really helpful!) All the articles I've read about sweep tests only seem to do sweep vs static shape, not sweep vs sweep for 2 moving objects. Are sweep vs sweep tests a common thing or even worth while? Any good (coder orientated) resources?
Hi. First post on this account. Very recent late Dx #ActuallyAutistic here. Special interests in my bio. Probably should include Autism as a special interest because I'm still in that phase. Nice to meet you. 👋

I got started, with thinking that OM is the radius of circle O and also the geometric mean of the pieces of the diameter of circle P.
What do you think of that? #geometry
Yet another classic, at last found its way to my library.
I'm wondering. If #computability and #unsolvability theories are mostly concerned with the existence of algorithms for classes of problems, if one could prove or disprove such a thing (class of theorems?) starting from #geometry.
I'll explain. I've recently understood (Steenrod et al, "First concepts of topology") that #topology is mostly concerned in proving existence theorems. The subject matter of this book sounds, in a way, like an attempt to prove such theorems. So naturally I came to wonder if anyone had attempted tackling them with topological means and tools instead. I haven't looked to see if this question even makes sense, but my humble instinct says that maybe yes, and that most likely at least someone has worked on it in the past.
I've taken up drawing again after decades of not touching pencils due to architecture school killing all the joy in drawing for me.
It's lovely and cathartic #drawing#MastoArt#Birds#geometry
Does #time have a direction? This physicist-philosopher says yes -- and that things get very interesting and might explain some conundrums if it's included that way in geometry.
An interesting article on this in Quanta Magazine.
Good evening, all you lovely logic gates, flickering out there in the dark. How about a challenge tonight?
You have a freshly generated cube sitting in front of you, aligned to the world axes (or axiseseses, if you prefer). You want this cube standing on one corner, with the opposite corner directly above it. How do you rotate the cube?
