Compare Four Forces:

The Four "Forces" article talks about the strong nuclear force, electromagnetic force and the weak nuclear force and gravity. It explains that gravity is no longer explained as a "force" in the Newtonian theory of gravitation. No gravitational force is acting at a distance to cause a body to accelerate as it is stated in the article. So it seems like what is being said is that the three forces, electromagnetic and the strong and weak nuclear forces are emitting a field which affects the behavior of distant objects, while gravity is no longer thought of in this way. The Newtonian idea was replaced with Einstein's theory of general relativity which states that two objects exert a force of attraction on one another known as "gravity." While one object is pulling you toward it, you are also pulling on that object and so kind of acting together in this gravitational way.

8/8/18 Bionics: The development of a bionic person and it's use in the military

8/8/18 Supporting Bionics for Humans? My first feeling about this topic is that I would support the option of bionics for humans in need of limbs, in place of old prosthetic limbs that have previously existed. I have not had to worry about this personally for myself or any of my family members, but I imagine that for someone who does, advances in science in this field are really important for having a more functional, happy life. I had a childhood friend who didn’t need a prosthetic limb, but was disabled and needed braces from the waist down as a child to assist with walking. These things were heavy, stiff, ugly and just archaic! It sounds like newer developments are moving toward more sophisticated options that are more accessible for average people. The UK based tech company mentioned in our readings is using 3-D printing technology to create prosthetic limbs which are more affordable. This sounds like a good thing. Especially for a child, being mobile and being able to do t...

7/30/18 I know I am a living system because..... Wow! Crazy how things can become not so black and white when you begin to look into what is considered a living thing. According to NASA, all living things share a carbon based chemistry, depend on water, or leave behind a fossil with carbon or sulfur isotopes that point to a past metabolism. Scientists struggle to define "life." From what I have read so far, it seems like something could be considered living and have certain characteristics of life, while others may be "alive"  and have slightly different characteristics. Crystals are interesting. They can grow and respond to stimuli but lack a nervous system. I believe there are many different forms of life and we can see things as living that are not what we would expect. In a Native American perspective even rocks are infused with spirit, is that a living thing?
