Hybrid Silicon Laser

 Intel News Release
Chip that Emits and Guides Light Could Drive Silicon PhotonicsInto Wide Use in Future Computers and Data Centers

Here is a story from JonnySpace. C:\>

When the Apollo 13 flight was jeopardized by unforeseen events, new
flight plans produced by computers were available in 84 minutes.
At the time, one person working on the problem could have performed
the task in 1,040,256 years. With a desk calculator, the time would
have been cut to 60,480 years.

Many people ask, how fast do computers operate JonnySpace?

Computers operate at speeds measured in nanoseconds (ns).
1 nanosecond = 1 billionth of a second. High performance computers
are capable of executing trillions of instructions per second. One
supercomputer built by a Japanese company has has a theoretical
maximum speed of 1 petaflop (1 quadrillion operations per second).

You may say, I can't conceive of how fast a nanosecond is. Help?

No problem. One nanosecond is to one second what one second is
to 32 years. One nanosecond is the approximate time required for
light to travel one foot
.

Is there any limit to the internal speed of a computer JonnySpace?

Electrical signals are propagated at speeds approaching the speed
of light (1 foot / nanosecond). Integrated circuits packing many
thousands of transistors per square inch have been designed to
minimize the length of the interconnections through which electrical
signals are propagated; this reduces the time it takes a signal to
travel from one transistor to another in the circuit. If signals are
propagated using light instead of electricity, speed and bandwidth
can be optimized. The only limit to the internal speed of a computer
lies in our minds perception and imagination of what a computer is,
and how it can be created.

I hope this will shed some light on the subject (pun intended).
You should now be able to realize the importance of the hybrid
Silicon Photonics Research.

A massive new collider could detect elusive subatomic particles and even hidden new dimensions.

Here is a story from JonnySpace. C:\>

The Large Hadron Collider, under construction on the Swiss-French
border outside of Geneva, will be the most powerful particle
accelerator ever built. It is encased in a 17-mile circular tunnel
hundreds of feet underground. Inside the tunnel two vacuum
tubes will intersect, allowing the protons to smash into each other
while instruments observe the spray of subatomic particles the
the collisions will release. Scientists hope to detect the smallest
particles that make up the universe.

Many people ask, just exactly what are these particles?

The current theory of particle physics, known as the Standard Model,
states that all matter is made up of 12 basic particles and all energy
is made of four more particles. Each of these 16 particles have an
anti-matter equivalent as well. Matter is made of electrons, neutrinos,
protons and neutrons, which are made of two types of quarks,
designated as up and down. The other particles, which existed
for only a fraction of a second at the beginning of the universe,
will possibly be momentarily re-created by the collision of protons
in the particle accelerator. When the particles crash together, scientists
are hoping, they will produce tiny fireballs of primordial energy,
re-creating conditions that existed when the universe was less than
a trillionth of a second old.

You may say, that's awesome, what else are they working on?

Scientists also hope to find evidence of an additional particle predicted
by the Standard Model but not yet observed. The Higgs boson is
believed to create a field that permeates space and gives other
particles their mass. It may be the cause of dark matter, which makes
the universe act as though it has a lot more mass than can be observed.
Many scientists believe that finding the Higgs boson is the next vital
step in particle physics.
