THE SAVING GRACE. “Finally, we have explicitly shown that the increase in black-hole entropy, which is a direct consequence of the (generalized) hoop conjecture, when combined with the Bekenstein entropy bound, ensures the validity of Bekenstein’s GSL in this historical gedanken experiment.” (GSL = the generalized second law of thermodynamics). https://lnkd.in/d3sfhP6 View in LinkedIn

ACKNOWLEDGEMENT. “In memory of Prof. Jacob D. Bekenstein (1947–2015), whose seminal papers have inspired my research.” https://lnkd.in/d3sfhP6 View in LinkedIn

THE PHILOSOPHER’S DILEMMA. “Very often, when we make general statements, there is an explicit or contextual restriction. ‘All ravens are black’ is a generalization about ravens. When leaving a plane with my wife, she might ask, “Were you sure to take everything?” Clearly that refers to the possessions that I brought onto the plane (and perhaps such of hers as she took me to be responsible for). So a negative answer would not be implied by my not having taken the inflight magazine or the airsickness bag from the picket in front of my seat.” https://lnkd.in/d9K-JQv View in LinkedIn

MATTER, ENERGY AND INFO. “Ask anybody what the physical world is made of, and you are likely to be told matter and energy. Yet if we have learned anything from engineering, biology and physics, information is just as crucial an ingredient.” https://lnkd.in/draqjTW View in LinkedIn

SOFTWARE. “The robot at the automobile factory is supplied with metal and plastic but can make nothing useful without copious instructions telling it which part to weld to what and so on.” https://lnkd.in/draqjTW View in LinkedIn

BIOLOGICAL INFO. “A ribosome in a cell in your body is supplied with amino acid building blocks and is powered by energy released by the conversion of ATP to ADP, but it can synthesize no proteins without the information brought to it from the DNA in the cell's nucleus.” https://lnkd.in/draqjTW View in LinkedIn

HIS THESIS SUPERVISOR. “Likewise, a century of developments in physics has taught us that information is a crucial player in physical systems and processes. Indeed, a current trend, initiated by John A. Wheeler of Princeton University, is to regard the physical world as made of information, with energy and matter as incidentals.” https://lnkd.in/draqjTW View in LinkedIn

PRIMACY OF INFO. “This viewpoint invites a new look at venerable questions. The information storage capacity of devices such as hard-disk drives has been increasing by leaps and bounds. When will such progress halt?” https://lnkd.in/draqjTW View in LinkedIn
