Light and Femto Photography

We started the class with a Ted talk about light. It was impressive to see how fast it travels, but in fact we can even see that. In the video, they slow down the action by 10 billion times, and in that way we can actually see the light travelling through a bottle of water. It is also talked about in the Ted talk the effect of light bounces. This can be used in our future for amazing creations like medical instruments, life savers for firefighters, and many many more ideas where light can be applied.
Comparing to photography, we talked about X-ray, which is a process that shoots radiation into parts of your body, that are able to travel through soft tissues, but not through hard issue like bones, so those bones are transmitted into a plate where the image is collected. The next process is the MRA, magnetic resonance is a picture of a slice through of whatever the doctors need to see, and that way see a picture of a tumor, bones, either soft or hard tissues. The doctors are able to move back and forward to see the image the way they need. The next creation is the FMRA where the tissues of the brain are easily observed. The FMRA proved that writing or hearing or reading something puts information in different parts of our brains, so the more ways we try to remember, the more areas in the brain is going to be. Another advantage of the FMRA is that, opposite to the X-ray, it does not radiate you body, a consequently bring serious health issues.
On the video showed during the Ted talk, there is a part where a tomato is showed, and even after the light is passes the vegetable, there is a very good scientific reason. The tomato, just like us is made by atoms, but there is more empty space than matter, so the light takes more time to go through the vegetable.

The last part of class was focused on how to manage Femto Photography. We mentioned that this should be a limited product, due to some negative effects. Another product that is already restricted is the cloning process of animals and cells. This is not available to anyone not only because of the price but also, and most importantly, the wrong usage a normal person could give to it.
