Baroque era concept blog

     This era brought about some major advancements that basically brought us out of the dark ages and into progress again.  I am going to focus on Galileo in particular because I do not have enough time to address much else in this blog.
     Galileo's theories and inventions kick started the baroque era and set the stage for things that were to be used for many years to come.  my favorite invention is his telescope or "looking device" that he called it.  He basically took an invention that nobody really knows who came up with and he improved upon it.  He being a mathematician knew that if you take one convex lens and a concave lens and place them at the right distance from each other, then you can magnify something by four times.  He later was able to improve upon this and get it to magnify up to twenty times!  this is the invention that he was able to use to prove that the Earth revolves around the Sun.  This is one of the things or maybe the one major thing that landed him in prison, but in my opinion it was the biggest improvement in science up to his time.
     I use this kind of looking device almost every time that I go hiking.  i call them binoculars, and of course they are drastically different from his original four power telescope, but it was kind of started with him an his unknown friend.  I am amazed that the scope on my rifle while also not exactly the same is basically based under the same principles.
     The other idea that Galileo came up with that we still use today was his concept of falling objects.  The idea that objects fall to the Earth at the same velocity regardless of size.  Up until his time, it was common belief that larger objects fall faster.  This was not too hard for him to prove this wrong.  He simple took two objects of the same matter (cannon balls for example) that were of different mass and dropped them from a fairly tall height.  The result time and time again was that they landed at the same time.  The only thing that might change this is air friction, but that is so slight that it is not noticeable with something like cannonballs from 100 feet.  He went on to show that this is also true with projectiles.  He used an experiment with cannonball again and this time he threw one outward, and the other one he just simply dropped straight down.  They to reached the ground at the same time. 
     The same holds true when shooting a bullet from a rifle.  Many people think that since a bullet can go up to one or two miles, that they will stay in the air longer when shot on a horizontal line.  The fact is the starts dropping the moment that it leaves the barrel and hits the ground at the same time as one  that would have been dropped out of your hand.  Of course this theory also is used today when people do things like bungee jump, or when a  sniper is aiming at a bad guy.

Enlightenment era

  I decided to do a blog about painting art for this blog.  One artist that got my attention was Jacques-Louis David (1748-1823).  I think that he was good at capturing real time events in his paintings.  my favorite is Napoleon Crossing the Alps 1800, oil on canvas.  It is one of four versions.   

Doug's new blog

Hello everyone!  I am just getting around to taking care of my homework because of a nightmare vehicle that has been taking up all of my free time (Doesn't start in the morning).  Now I am ready to get on track, I did most of the reading before the semester started, so now I am going to post a couple of blogs so that  I can get familiar with this and have my assignment for the week done.  I plan on having this next week's done a little sooner this time.  My URL is             doug556h.blogspot.com
PS Is there a spell check for this program?
Thanks,
Douglas
