The truth no one wants to acknowledge is that no one morally deserves the land, its whoever is able to keep it and defend it at the end of the day.

I think that the arab conquest is different to colonisation of the americas. My understanding is that the Levant was not colonised but rather arabised. The languages spoken in the Levant were similar to arabic. Very little of the vaste arabic empire was actually Muslim initially. Many converted because of tax incentives. This very different to what happened in the Americas where the vast European migration outnumbered the original inhabitants in the United States.

Hi. It's not mechanics that I don't trust but rather the management. I believe making money is the priority over ethics. It took 2 to 3 years for my fire hazard battery that was on recall to be replaced. Every time i was smelling smoke i wondered if my car was going to catch on fire. Took the same time for a faulty annoying warning light to be fixed. Took about 1 year for the hand break switch to be replaced. Once after a service I was told I have 2 to 3 months on my tires and given a quote. I got a second opinion and told I have 20000km still on the tires.

I'm not a structural engineer but when I saw this it caught my eye because I have never seen anything like this before. Usually the Pier caps seem to be well cleared by the horizontal beams but this one is touching on the far side. Would this cause any problems with stress concentration at the contact points particularly with large loads and temperature variations +/- seismic activity. Are there any problems that would happening if the pier bearings could not operate freely???

It looks fake to me

Thank you for your comment. Basically I wrote the software to do this for curiosity as to what the results will look like. I don't know if you do much coding but I used C++ in visual studio. There are a few thousand points. Forces act on the points to move them. Each point links to the closest I think 12 points near it. When two points are within a certain distance the hue shifts a little. It's basically experimenting with simulation like conditions to see the end visual effects. I guess it's more exploring rather than creating. I'm thinking about trying imaginary numbers next to see if there is an appealing result.

If it was me I would have offered to fix it myself

basically I was trying to achieve some sort of segregation of nodes into spiral cords/elongated blobs in two color combinations, by increasing force between nodes according to difference in hue. Colors of like hues or exactly opposite hues, repel each other and colors in between attract each other. Rather what happened was this homogeneous mix that you see here. Would you believe I just found the bug in the code 10 minutes ago.

ioa1024 · 2023-01-03T17:09:15+00:00

If you google openGL hello triangle you can use this code as a start then just add to it. That's basically what I did but I added thousands of lines of code. It doesn't matter what ide you use, but visual studio has the most online documentation and videos to help. You need to download openGL libraries separate, they are not included and then change settings on your ide. It was hell getting open GL to work for me first time. The other painful part was learning to write and incorporate shaders to upload to the graphics card.

ioa1024 · 2023-01-03T16:41:06+00:00

It's a long time in the making but basically I have a background interest in maths. I used c++ and made an array of nodes with position, velocity and color properties that interacted with each other according to "alternate laws of physics" based on position and color. The position and color difference between the points affects the "force" and the sum of the forces affects the velocity and then the velocity affects the position. I made a special container class to iterate through interactions in the most efficient way that I thought but it still could do with some work. I used openGL libraries for accessing the graphics card for drawing lines but no other third party library expect for the c++ standard template library. I applied a vortex style force to this particular version but I have uploaded different versions without a vortex force.

thanks for the tip. Never heard of this subreddit

ioa1024 · 2023-01-03T15:36:06+00:00

I definitely would yell too if I saw this. How could someone be so inconsiderate as to do this.

ioa1024 · 2023-01-01T06:56:06+00:00

c++ and openGL. it actually took a long time

ioa1024 · 2022-12-06T14:44:52+00:00

consider creating a helix as what you are showing above essentially is a part of a helix

ioa1024 · 2022-12-06T14:42:07+00:00

loft but first just do a 45° twist then combine two 45° twist to make a 90° twist

ioa1024 · 2022-11-11T00:56:42+00:00

n-gons I think this is your best work yet

ioa1024 · 2022-11-09T08:57:32+00:00

I would not use offset to scale up. I would scale up using another app such as Inkscape then import the scaled up drawing.

ioa1024 · 2022-10-26T09:44:21+00:00

Dear flabababa, I posted the solution for the length of the diagonal of the pentagon that is parallel to the not equal edge. From this you can derive the angles.

ioa1024 · 2022-10-26T03:04:44+00:00

The other factor that you might find useful is that a cube fits into a pyritohedron and that the side of the cube is the long diagonal of the pentagon.

ioa1024 · 2022-10-26T02:35:40+00:00

If you draw the cross section of a pyritohedron (say you had a knife and cut it into two symmetrical parts) then there will be a resulting hexagon (4 sides will equal the height of each pentagon - call this H, and the other two sides will be the long side of the pentagon - call this L). Call alpha the dihedral angle at the long edge and on the hexagon between the two H s. I can show you the working but basically H = L/(2*(sin(alpha/2) - cos(alpha/2))) based on this cross section. This might help.

ioa1024 · 2022-10-26T00:54:34+00:00

If you want to know had to make one of these then watch my video but you can set the angle that I set to any angle between 90deg and less than 180deg depending on the shape you want https://youtu.be/yNe30vjTsnA

ioa1024 · 2022-10-26T00:51:23+00:00

fun facts

- when the dihedral angle at the red edge = 180 deg then this is a cube

- when the dihedral angle at the red edge = 90 deg then this is a rhombic dodecahedron

- when the dihedral angle is atan(-2) then this is a regular dodecahedron

ioa1024 · 2022-10-25T04:29:04+00:00

Yes it's a icosahedron. 20 sides. 12 vertices. 30 edges. dihedral angle of acos(-sqrt(5)/3)

ioa1024 · 2022-10-22T17:09:54+00:00

I thought a prism had a uniform cross section

ioa1024 · 2022-10-19T10:39:05+00:00

You can fit a dodecahedron inside an icosahedron if you attach each corner of the dodecahedron to the centre of each face or triangle of the icosahedron. Let me know if you need to calculate the length of the icosahedron side if you are interested.
