Some consider the removal of Dr. Mohammed Morsi a coup by the army against an elected president. Others treat it as the second revolution, or the continuation of the January 25, 2011, revolution.
It turns out all molecular and biological systems have speeds of the atoms move inside them; the fastest possible speeds are determined by their molecular vibrations, and this speed is about a kilometre per second.
Once we understand how molecules are formed, we can manipulate them. If you can manipulate molecules, you can manipulate genes and matter, you can synthesize new material - the implications are just unbelievable.
I am not one of the new media experts working all the time with my computers and the PowerPoints and things of that sort.
On the banks of the Nile, the Rosetta branch, I lived an enjoyable childhood in the City of Disuq, which is the home of the famous mosque, Sidi Ibrahim.
I teach at Caltech and oversee a research laboratory there. In general, I find that the majority of young people are excited by the prospects of research, but they soon discover that in the current market, many doctorate-level scientists are holding temporary positions or are unemployed.
On Sunday August 5, 2012, I was among a group of people who witnessed the Rover landing on Mars in real time at NASA's Caltech-managed Jet Propulsion Laboratory in Pasadena.
As a boy, it was clear that my inclinations were toward the physical sciences. Mathematics, mechanics, and chemistry were among the fields that gave me a special satisfaction.
Curiosity - the rover and the concept - is what science is all about: the quest to reveal the unknown.
The mosque was the neighbourhood house of worship, but it was also the place where my high school friends and I came to study.
After World War II, scientific research in the U.S. was well supported. In the 1960s, when I came to America, the sky was the limit, and this conducive atmosphere enabled many of us to pursue esoteric research that resulted in America winning the lion's share of Nobel Prizes.
Secularism will not work in Egypt any more than theocracy. What will work is governance that is guided by the Islamic values of the majority with protection of the minority rights.
Some leaders think time will solve the problem. Their hope is that Assad's regime will ultimately fall from the heavy toll of the horrors it has spawned. From past experience with such regimes, this scenario is unlikely to happen.
For years, the West supported Mubarak and gave aid for what it hoped was stability - but was actually stagnation - in the Middle East.
From the dawn of history, science has probed the universe of unknowns, searching for the uniting laws of nature.
I discovered how science is truly a universal language, one that forges new connections among individuals and opens the mind to ideas that go far beyond the classroom.
There is little doubt that an unstable Syria will destabilize the whole Middle East.
Egypt was the first democracy in the Middle East. Women were unveiled in the 1920s. Egypt is a country of civilization, of culture. It shouldn't be suffering.
Besides being a prime cause of poor economic growth, poor governance breeds corruption, which cripples investment, wastes resources, and diminishes confidence.
