Hi fellow alumni,
An interesting eye exercise.
Hope that it works for you as it has done for me.

Build Up Better Vision by Martin Sussman

"How Flexible Are Your Eyes?"
Those of us who are near- or far-sighted have a rigid focusing system so that the muscles that control our ability to focus are more stiff and inflexible than they need to be to focus clearly.
TRY THIS NOW: (without glasses or contacts)
Hold your hand up near your face and focus on it, and then quickly look at something past your hand in the distance. Then look back at your hand. Out of the corner of your eye notice the same distant item.
If you've got clear vision, here's what you should see:
Your hand will be clearer than the distant item when you are focusing on your hand. When you're focused on the distant item, it will be clearer than your hand.
However, if you're nearsighted, your hand will be clearer, even when you're looking at the distant item.
And if you're farsighted, the distant item will be clearer, even when you're looking at your hand.
In other words, if you've got a vision problem, your eyes can't change focus, swiftly, easily and sharply, from far to near.
Many people think there's nothing that can be done about that, perhaps even believing that it's because the eye is the wrong shape (that's another one of the 5 Vision Myths that I tear apart in The Program for Better Vision).
But you can train the muscles in your eyes to focus better at different distances, and here's why:
FATTER OR FLATTER:CAN YOUR LENS MAKE THE CHANGE?
The lens in the eye changes its shape to bring objects into focus. The lens needs to be flatter to see objects that are further away more clearly. And it needs to become fatter to focus on something closer.
We are always changing what we are looking at, so the lens is continually making fine adjustments in its shape.
Normally, the lens changes its focus - and thus its shape - more than 100,000 times each and every day.
The shape of the lens is controlled by a group of muscles that surround the lens. These muscles have to work together to change the lens into the exact shape required to bring whatever you are looking at into sharp focus.
This changing of the eye's focusing power is called Accommodation. (It's one of the 6 Critical Visual Skills you'll develop when you use The Program for Better Vision.)
But if you've got a vision problem, these muscles around the lens become stuck and stiff. Some of them can't relax when they need to, while others can't stretch when they need to.
If you're nearsighted, they're stuck for near vision and the lens has too much power. On the other hand, if you're farsighted, these muscles are stuck for distance vision; the lens has too little focusing power.
Like any other group of muscle in the body, the muscles around the lens can be exercised. When you exercise them correctly, they can regain flexibility and tone, and they'll work the way that they're supposed to.
Here's one exercise from The Program for Better Vision that re-trains accommodation: Near-To-Far Shifting.
TRY THIS NOW: (without glasses or contacts)
1. Look at your finger, about 4-6 inches in front of your eyes.2. Shift your focus to a distant target, at least 10 feet away.3. Shift your focus back and forth from your finger to the distant target 10 - 20 times.4. Repeat as many times during the day as you remember. The more the better!
Make sure that your focus rests for a brief moment before you shift your vision again.
With practice, you'll be able to train the muscles around the lens to become more flexible and to change focus more easily and quickly. The result: You'll see better and better through an increasing range of distances.
Near-To-Far Shifting is one of 24 different exercises, techniques and processes that you'll find in The Program for Better Vision.

Semiconductor Industry
Dear fellow alumni,
Today, I would like to share a personal experience with you.
My personal experience in the Semiconductor industry started two decades ago at AMD. At that time, I was so "green" that I do not realize that I was venturing into an industry that was going to shape the way we do business, change our lifestyle and communicate. It was so new to me even when it was already 4 decades old. Everything looks so new to me.
So, it struck my mind to share this article with all of you, just in case you have not heard about this industry.
As time pass, I realized that this is a fast paced industry. The pace was governed by Moore's Law (A 1965 prediction by Gordon Moore, Intel's Co-Founder). Moore's Law, states that the number of transistors on a chip will double about every two years. Intel has kept that pace for almost 4 decades, leading the way and on hot pursuit by other Semiconductor manufacturers (source: http://www.intel.com/technology/mooreslaw/ ).
To most of us, we take for granted that mobile phones, LCD TV, DVD player, MP3 player, computer and digital watch are just ordinary inventions out of needs. But, I would like to point out that these miracle electronic gadgets would not be invented if the silicon-germanium junctions transistors were not discovered.
The Semiconductor history started with the discovery of the Si-Ge transistor by John Bardeen and Walter Brattain of Bell Laborotary in 1947. The discovery paved the way to miniturisation of gadgets. Today, the central processor unit (cpu), the brain of a computer is only 2" x 2" x 0.25" in size, weighed only 100 grams and constructed over 800 million transistors. The first computer, ENIAC weighed 27 tons, was roughly 8.5 feet by 3 feet by 80 feet (2.6 m by 0.9 m by 26 m), took up 680 square feet (63 m²) of space was commissioned in 1946.

The Semiconductor industry is ranked 20 out of the Standard & Poor Top 500 Ranking, registering monthly sales of US$ 23 billion until Sept., 2008 when the world faced an economic meltdown Sales after then had been sluggish and demand for Semiconductor chips had suffered a drastic decline.

Anyway, we would not have computers, laptops, PDA, cell phones, blackberry, digital cameras, ipods, calculators and many other gadgets without Semiconductor industry. Imagine a world without them. Maybe life would have been simpler.
Embeded within these gadgets are semiconductor chips made from silicon wafers and interconnected with tiny aluminium, gold and copper wires of sizes as small as 20um diameter, ten times smaller than the human hair by wire bonders.
The following video shows a wire bonder in action. This equipment is capable to placed 100 mils long gold wires of 25um diameter at the rate of 16 wires per sec.
Let us hope the economy will improve by end 2009 and more trendy gadgets will be available by then. Till then.
Cheerios!
