Jeremy Britton, a civil engineer, needed help from an expert physicist in using spacetime diagrams to help the reader visualize spacetime. While he was able to achieve the correct graphs for flat spacetime, he was looking for help in plotting the curves for curved spacetime.
How Kolabtree helped
Jeremy posted his project on Kolabtree and received a bid on the same day from Dr. Lester Ingber, one of Kolabtree's most accomplished scientists.
About the expert
Dr. Lester Ingber is an interdisciplinary physicist with a wide range of accomplishments to his credit. He has published over 100 papers and books in theoretical nuclear physics, neuroscience, finance, optimization, combat analysis, karate, and education. Through Lester Ingber Research (LIR) in Ashland, Oregon, he develops and consults on various physics projects. He is currently Principal Investigator (PI) of the National Science Foundation collaborative supercomputer resource, The Extreme Science and Engineering Discovery Environment.
The client and freelancer discussed the scope and deliverables of the project using the private message board. The project was successfully completed within five weeks.
I've used Kolabtree twice to find excellent physics experts and have worked with them on my popular science articles.
