I was curious as to what was the number of dimensions that we know of and found out that depending on the theory that is being used there is a different amount. Superstring theory suggests a minimum of  10, M- Theory suggests at least 11, and bosonic string theory says 26. What I thought had the potential to be an easy question wasn’t so easy.  The link to this article explains the 10 dimensions. https://phys.org/news/2014-12-universe-dimensions.html If you do not feel like clicking on it I will make a simplified list.  1st Length, 2nd Height, 3rd Depth, 4th Time, 5th Possible Worlds, 6th A plane of all possible worlds with the same start conditions,7th A plane of all possible worlds with the different start conditions, 8th A plane of all possible worlds, each with different start conditions, each branching out infinitely,9th All possible worlds, starting with all possible start conditions and laws of physics, and finally 10th infinite possibilities.  I didn’t think the list to bad until I got towards the end starting at number 5 I tried imagining what that would entail and I think even then all possible worlds is pretty vast and quite large.

The math and history in blacksmithing, focused around damascus.

I have always had a passion for blacksmithing and being able to take one thing and craft it into something else. What I find very interesting is the process that goes into handcrafting knives out of different materials and different material mixes to achieve a certain strength or weight or really any variation. For example a person on youtube that does Damascus smithing is Alec Steele. With math and logic he creates various patterns into the things he builds. What is Damascus? It is a mix of two different metals to give a pattern. After forging your piece it gets dipped into Ferric Chloride for a period of time varying on the darkness of the etch you’d like. Everything about blacksmithing is interesting because the list of things that can be forged is very long. Blacksmithing is very math intensive with the measurements, the shape, the weight ratios from the blade to the handle to make sure it is balanced. The following images are a few of the patterns he has made.

Origami in Medicine

While watching the documentary on origami I found it very interesting to see the practical uses of origami. It was interesting to see how it could be used in medicine, space and even our vehicles. I found the medicine one more interesting for the fact that we are using folds to minimize the size of an object to help with inserting it in the body and once heated by the body it expands. Like the stint that we saw, they used to use balloons according to the documentary now they can use an object that is durable and strong enough to withstand time. With the new developments made by origami such as the stint I think it will be incredible to see how far it takes the medical field and other fields. http://www.origami-resource-center.com/images/usefulOrigamiStent.jpg

Dungeons and Dragons Platonic Solids

So we had to post about things we talked about in class, I was thinking of what kind platonic solid I could talk about and so went to google for inspiration. I saw some dice that reminded me of the kind of dice I have for a game called Dungeons and Dragons. I am sure most people have heard of it if not by the game being popular or through the popular show The Big Bang Theory. I went and took my game dice out.

As you can see from the picture the common dice throughout the game called d4, d6, d8, d10, d12, d20. The d20 which is the second one from the bottom in the picture is the platonic solid triangle which 5 meet at the vertex. The d12 is a pentagon which 3 meet at the vertex.  The d8 is 4 triangles that meet at the vertex. The d6 is a cube, and the d4 is a triangle that 3 sides meet at the vertex.

Rosettes in life

After we had finished class I thought I would pay attention to the different rosettes that may be around me on my walk back to the dorm. As I thought more and more about looking at various things, I noticed there were a lot more than I believed. The first thing I noticed was one of the man holes on the sidewalk. I noticed this one had a honeycomb pattern if you will, but it has writing in the middle. So if the writing wasn’t there it could be rotated twice, once 180 degrees and then the full 360. It also can be mirrored once if you roughly go vertically between the two holes. This would make it a dihedral 2

I also looked at car rims because the patterns are usually the same throughout the whole rim. The thing that was stopping them from being a rosette was the logo’s in the middle. That lead me to think about the various car logos that I know. Here is a small list of the few that would work. Mercedes, Audi, Mitsubishi, I believe Hyundai, and BMW. This rim would be a dihedral 3 because it has three lines of reflection using the Mercedes logo as the point of reflection.


Hi everyone,

I am Kevin Murray. I am hopefully posting this in the right place this time. I am a Homeland Security Major in my Junior year. I transferred from WMCC in Berlin, NH and I live in Pittsburg, NH. I am currently residing at the NHIA dorms in Manchester because Pittsburg is 3.5 hours away so commuting was not an option.
