When and why did people first start using money? – Kyle Weissenberger

This article written by Chapurukha Kusimba describes money as a universal language, something that everyone, everywhere understands. Starting in the upper Paleolithic nearly forty thousand years ago, individuals would barter for weapons and tools, creating the first forms of currency. The article describes that the common belief is that money first originated as a form…

Comment on Tarkov- Engineering the Erie Canal by David Barney by weissenbergerkyle

Great job summarizing the article. I personally think it’s very interesting to find that the need for engineers for public creating could have had such a profound effect on the educational systems in America. Reading about the 5 locks and 60 foot elevation change within just peaked my curiosity. I did some research and found that in total, the Erie canal has 36 locks and and elevation difference of around 550 feet.

Nice work Max, I really appreciated how detailed yet completely understandable your descriptions of the engines were. The included images and animations were helpful too.

It’s interesting to me to think about how these devices were created without scientific backing, through mere trial and error.

Comment on Fisk, “Arkwright” by weissenbergerkyle

You did a wonderful job with this post, It read like a story and was very entertaining. From what you wrote it seems like Arkwright lead a rather interesting life. I too was pleased with his values for education, children, and general philanthropic tendencies.

Also on the second link, I found it rather funny that his creation of waterproof wigs helped him finance his spinning devices.

Comment on Qasim Wani: Gimpel, Chapter 7 – The Medieval Machine: The Mechanical Clock by weissenbergerkyle


This is an expertly written post, well structured covering everything from background information, problems, progress, to the ultimate solution. I really liked your detailed description of the shortcomings of previous time keeping devices. The included video was very informative, I really enjoyed the candle burning method.

All this clock-talk reminded me of the youtube channel “Clickspring” which details the build process of many different clocks. He is currently recreating the Antikythera mechanism that Barbara Reeves introduced us to. If you are an engineer, you will enjoy this channel.
