Hungarian born American chemist, George Andrew Olah wasa prolific researcher. The central theme of his career was thepursuit of structure and mechanisms in chemistry, particularlyfocused on electron-deficient intermediates. He leavesbehind a large body of work comprising almost 1500 papersand twenty books for the scientific community. Some selectedworks have been published in three aptly entitled volumes,Across Conventional Lines.
There is no way to capture the many contributions of Olah ina short essay. For this appreciation, we have chosen to highlightsome of those contributions that to our mind representa significant advance to the state of knowledge.

Multi-core microprocessor is an interconnected set of independentprocessors called cores integrated on a single siliconchip. These processing cores communicate and cooperatewith one another to execute one or more programs faster thana single core processor. In this article we describe how andwhy these types of processors evolved. We also describe thebasics of how multi-core microprocessors are programmed.

We present a ball game that can be continued as long as wewish. It looks as though the game would never end. But byapplying a result on trees, we show that the game nonethelessends in some finite number of moves. We then point out somedeep results on the natural number system connected withthe game.
