M. C. Escher,

17 June 1898 – 27 March 1972) was a Dutch graphic artist who made mathematically inspired woodcuts, lithographs, and mezzotints. Despite the wide popular interest, Escher was for most of his life neglected in the art world, even in his native Netherlands. He was 70 before a retrospective exhibition was held. In the late twentieth century, he became more widely appreciated, and in the twenty-first century, he has been celebrated in exhibitions around the world.

American computer scientist who created ALOHANET, the first modern data network, which formed the basis of the protocols essential in the Ethernet now in wide use. It opened in 1970, operating at 9600 bits per second, using radio to provide a wireless packet-switched data network between several Hawaii islands. Its innovations included the first packet radio sensors, the first packet radio repeaters, the first satellite packet network and the first radio access to the Internet.

Wernher Magnus Maximilian Freiherr von Braun 

23 March 1912 – 16 June 1977) was a German and American aerospace engineer and space architect.

Von Braun is widely seen as the "father of space travel", the "father of rocket science" or the "father of the American lunar program". He advocated a human mission to Mars.

As a young man, von Braun worked in Nazi Germany's rocket development program. He helped design and co-developed the V-2 rocket at Peenemünde during World War II. The V-2 became the first artificial object to travel into space on 20 June 1944. Following the war, he was secretly moved to the United States, along with about 1,600 other German scientists, engineers, and technicians, as part of Operation Paperclip.

He worked with Walt Disney on a series of films, which popularized the idea of human space travel in the US and beyond between 1955 and 1957.

In 1960, he served as director of the newly formed NASA Marshall Space Flight Center and as the chief architect of the Saturn V super heavy-lift launch vehicle that propelled the Apollo spacecraft to the Moon. In 1967, von Braun was inducted into the National Academy of Engineering, and in 1975, he received the National Medal of Science.

Dedicated to Brahmagupta

Born c. 598 CE, died c. 668 CE) was an Indian mathematician and astronomer.

Brahmagupta's Brahmasphuṭasiddhanta is the first book that provides rules for arithmetic manipulations that apply to zero and to negative numbers. The Brahmasphutasiddhanta is the earliest known text to treat zero as a number in its own right, rather than as simply a place holder digit in representing another number as was done by the Babylonians or as a symbol for a lack of quantity as was done by Ptolemy and the Romans.

Dedicated to Albert Einstein, was born on March 14, 1879.

Work was inspired by Pi (π). Pi is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi".

Hot Pi 2 is a second work recognizing Pi. Pi 2s composition has the two circle merging together in a more dominate composition.

Synchronicity: Coincidence in time; contemporaneousness; simultaneousness.

Synchronicity is a concept, first introduced by analytical psychologist Carl Jung, which holds that events are "meaningful coincidences" if they occur with no causal relationship yet seem to be meaningfully related. During his career, Jung furnished several slightly different definitions of it.Jung variously defined synchronicity as an "acausal connecting (togetherness) principle," "meaningful coincidence", and "acausal parallelism." He introduced the concept as early as the 1920s but gave a full statement of it only in 1951 in an Eranos lecture.

Happy birthday: Sigmund Freud, 6 May 1856

Ernest Orlando Lawrence (August 8, 1901 – August 27, 1958) was a pioneering American nuclear scientist and winner of the Nobel Prize in Physics in 1939 for his invention of the cyclotron. He is known for his work on uranium-isotope separation for the Manhattan Project, as well as for founding the Lawrence Berkeley National Laboratory and the Lawrence Livermore National Laboratory. Chemical element number 103 was named lawrencium in his honor after its discovery at Berkeley in 1961.
