Transcript

So recently professor Bowley showed us log tables; how in the good old days he used to use books like this to do big calculations. I'd suggest having a look at the video before watching this one if you need to get up to speed, but at the end of the last one we promised we talked about how these tables were created. Now the log tables we were lookin... Read More
