Code and Carrier Safety

For our project where we are using DNA to code for messages.  The idea is to inject cells with the DNA into a human who can then transport the message onward to others who will be able to isolate and identify the code.  This will allow for numerous layers of defense:

1. Existence of the code

The "enemy" would have to know of the existence of the code in order to try and decrypt it.  This new tactic we are using would likely remain secretive for a time simply because of the novelty of this idea

2. Identifying people who have it

Human brain has the ability to store and transmit memories using images. There is specialized area in the brain called Hippocampus that is involved in storage and generation of memories. The way memories are sored is still not quite understood. However, it is speculated that visual or any other stimuli that a person perceives is accompanied by production of proteins in the brain that are involved in generation of new neuronal connections in the brain.

War!

So for my part of the project, I will focus on the threat to our country's infrastructure namely the electricity grid and water systems. This idea stems from Alan Turing's prominent role in helping to decipher German codes. Considered the father of computer science and AI, Turing was a English mathematician, logician, cryptanalyst and computer scientist. He invented the Turing Machine, solidifying the concepts of algorithms and computation, a step-by-step procedure for calculations.

Alan Turing’s Historical & Contemporary Impact on War

On September 3rd of 1939, Britain declared war on Germany. Within one day, Alan Turing arrived at the British codebreaking house in the town of Bletchley (just between Oxford and Cambridge). It was there that he worked with another Cambridge mathematician by the name of Gordon Welchman to design the Bombe, a machine to break Enigma-enciphered messages sent by the German military. This was just the first of five major cryptanalytic advances that Turing developed during World War II. These many contributions have been credited with shortening the war by several years.

Alan Turing and Fibonacci Numbers

Alan Turing was a mathematical genius. He speculated that there was a relationship between math and nature through the presence of Fibonacci numbers that naturally occur in plants.  Fibonacci numbers are a sequence of numbers, where you can add one of the numbers with the number to the right of it, to get the next number.  For example, the first few numbers of the sequence begin as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, etc.  To get the number after 21, simply add 13 to 21, which gives you 34.

Artificial Intelligence: Kismet the Robot

 

Alan Turing is seen as the father of computer science and artificial intelligence, which is why my group decided to focus on artificial intelligence.  I will specifically focus on Kismet, a robot made at MIT that has many human qualities such as speech detection, speech, emotion / facial expression, and vision. There are many aspects of artificial intelligence such as general intelligence, social intelligence, perception, learning, and planning.  Kismet in particular has social intelligence.

Final Exam- My Portion

For our final project, I am in the group which will, in the spirit of Alan Turing, offer a new method in which to encode messages.  Unlike other codes, our code will be biological, and will be encrypted in DNA itself.  Our method involves encoding a message using some sort of encryption with nucleotide sequences and implanting this sequence into the body of the messenger.  The recieving end will know where to look for this particular message.  For my portion of the project, I will create

Chemical Morphogenesis and Animal Patterning

Alan Turing's contribution of chemical morphogenesis, the creation of form and shape during animal development, led him to propose a reaction-diffusion model as the basis of the development of patterns such as the spots and stripes seen in animal skin. By understanding the cellular mechanisms of morphogenesis, we are able to use the proposed model to examine the patterning of animals. For example, why do zebras always have black and white stripes?

Jing (Sophie) Xia- Alan Turing and Fibonacci Numbers

Our group will study Alan Turing's Fibonacci Numbers and I will specifically focus on Natural Occurrence of Fibonacci Numbers in pine cones and plant leafs. Pine cones display the Fibonacci Spirals clearly. The best way to examine these patterns is to observe pine cones form the base where the stalk connects it to the tree. For instance, one set of spirals go in one uniform direction whereas another set of spirals go in the opposite direction (see images below). In one direction, we count 8 whirls whereas in the other direction, we count 13 whirls. Both 8 and 13 are
