Vectors are defined in the video as a very basic idea, anything that has size and direction is a vector, some examples are velocity, where force moves something with mass. Newton's second law F=ma is a description that includes two vectors, force and acceleration, The description of vectors in a static system where forces are balances and pushing against one another is also a great demonstration.
Dark matter is a video that leaves as many questions as if offers answers, but is probably my most favorite video as it discusses something that is extremely interesting and elusive. The fact that 95% of mass is either dark energy or dark matter and only about 4% is "normal" matter (containing everything we know) is a staggering statistic. The fact that everything we know is affected in some way by electromagnetic energy and that dark matter is only very limitedly affected by or affective of electromagnetic energy is also a point I found really interesting. Much of what was said in the video explains why dark matter is so fascinating to people, experts and laymen, as it is present all around and even within us but is almost completely undetectable ad can be detected only by the fact that it has mass and affects gravity.
MRI was a video that I found challenging as the science was not well explained, though the visual imagery is stunning. The pictures of the inside of human brain are fundamentally influential on the way we see ourselves in the modern world and the better the technology gets likely the better the understanding of how we think and really exist. I would like to see the video with better scientific explanations, though...
Interactivity in Video Games and Movies Information technology has changed the way we live in today's world. Everything from our television to our cell phones are connected through network medium. Computers define the way we do many of the things in our lives, such as, how we maintain our bills and expenses to even conducting business activities online.

Pervasive Video Games as Art The form and function of art has evolved and changed quite a bit over the years, decades and millennia. Paintings and sculpture have been artistic mainstays for much to most of the world of the civilized human race. However, with the technological revolution that has roared up over the last fifty years or so, new forms of art have bubbled to the proverbial surface. Digital technology
There is plenty of anecdotal evidence to support this theory -- several prominent school shootings have been ostensibly linked to video game playing -- but real scientific evidence is also emerging that suggests a more subtle but similar effect. In one study, college-age participants who had spent time playing Wolfenstein 3D, a first person shooter computer game, "punished" their opponents by subjecting them to loud noises of high intensity more
Law enforcement and corrections can be influenced by several external threats. These consist of external communication gaps and many environmental influences. One of the key external threats that impacts both corrections and law enforcement is politics. In delineation, politics is the art of wielding one's authority and power over the government or public affairs. In particular, political action can give rise to the imposition of one's interests within the government,
Parents think school is the best place for a child to learn and to grow. People often believe traditional schooling is an effective way for a child to learn and grow. However, in recent times people have discovered traditional schooling may not be as effective as one believed. Colombo, Cullen and Lisle discuss in their book the pitfalls of formal classroom instruction. Formal classroom instruction may be useful for some
Technology can be used to enhance learning An oral presentation used to present information and teach individuals about a particular concept. Lecture is often used to convey critical information. An investor presents his investment thesis and rational to an economics class. The investor, teaching the basics of Finance, provides the class with a copy of his lecture notes and slide Video and websites provide visuals to better allow student to learn. Video
