Pipelining increases performance and instructions per cycle, but at the cost of power efficiency as branches cause a pipeline flush.

The problem is balancing area, performance, and performance.

There are obviously limits the the ability to make smaller circuits, even the ones described as 14nm are not really 14 in the same way 160 was 160. There is a lot of wasted space because of the LELE process and the need to minimise crosstalk and distortion.

The real limit however is not how much better X-ray exposure will shrink the size, but how much it costs to make circuits, 28nm is likely to be the most cost efficient size for some time to come. Many fabs are making chips in larger process sizes for fast turnaround and cheap masks.

Some theories for the end of the universe say that if the expansion of the universe keeps accelerating, eventually the expansion even between subatomic particles will be greater than the speed of light and everything will be ripped apart. This is long long after the skies are black because all objects and space have moved too far away.

This is one of those topics that attracts loonies like flies to honey. Of course in the comments below, each side thinks the other side crazy too much control or too irresponsible.

For me, I think everyone should be vaccinated for common and dangerous diseases. The uncommon ones you can chose to or not (as when traveling). People don't remember polio and smallpox or brain-damage caused by measles.

“I would not hurt you, little man,' he said.

'I think that I got the disorder in Mullingar,' I explained. I knew that I had gained his confidence and that the danger of violence was now passed. He then did something which took me by surprise. He pulled up his own ragged trouser and showed me his own left leg. It was smooth, shapely and fairly fat but it was made of wood also.

'That is a funny coincidence,' I said. I now perceived the reason for his sudden change of attitude.

'You are a sweet man,' he responded, 'and I would not lay a finger on your personality. I am the captain of all the one-legged men in the country. I knew them all up to now except one—your own self—and that one is now also my friend into the same bargain. If any man looks at you sideways, I will rip his belly.'

And then a question you answered in more detail is marked down because you included content not covered in class, or a question requires the exact quote from the lecture instead of the facts, or your teacher is just wrong about the facts and criticizes you for disagreeing, or you answer all the questions on a test and the rest of the class is given D's because the test is on the curve.

Clean water from hundreds of miles away is contaminated and them it flows into salty ground (see Australia for an example of this.) Some of it evaporates and descends as snow or rain far away from you. A small amount is retained deeper in the ground which would be great for some plants, but not so good for tomatoes or grass.

Water is not destroyed, but you have to pay for more for the next irrigation cycle.

It might as well be destroyed. If this were not true there would not be such a debate on the volume water extraction from rivers and aquifers.

I agree with rational wiki and others:

"While Spencer has become an ID PRATT machine, he hasn't contributed any new cards to the creationists' deck. He mostly just parrots the greatest hits like "no transitional fossils" and "microevolution not macroevolution." He also flogs the "secular religion" trope even harder when it comes to evolution than he does for global warming."

Evolution denier is even looper than doubting isotope dating. Yep, religious agenda. From his comments on "The Evolution Crisis":

"To examine the relationship between science and the Bible, a good place to start is with the origin of the universe. Science presents us with the laws of thermodynamics, the first of which states that the total amount of matter and energy in existence is constant. If this were the only natural law to be satisfied, it would be possible to believe that the universe has existed forever. Indeed, that was the prevailing view back in Darwin's day. However, the second law of thermodynamics states the overall amount of useable energy is constantly decreasing – it is being degraded into a less useful form. In other words, the universe is dying. If the universe were eternal it would by now have experienced what astronomers call a 'heat death' – a state of total equilibrium in which entropy would be infinite. This, among other factors, has led a majority of astronomers to agree that the universe had a beginning. Several thousand years of scientific endeavour has brought the majority of scientists in line with the first verse of the Bible which states, "In the beginning God created the heavens and the earth." Well, the first three words of the verse anyway! If there is no God, who or what caused the universe to begin? There really are only two basic options – it created itself out of nothing or it was created by something greater than itself! If everything that begins to exist has a cause, and the universe began to exist, the universe must have had a cause."

"A second issue is the origin of life. There is a vast gulf between the most complex non-living compound such as a crystal and the simplest form of life such as a bacterium. The gap is much larger than the gap between a bacterium and a human being. Science, despite expending enormous amounts of time, is actually further away from an explanation as to how non-living chemicals can accidentally and spontaneously come alive than it has ever been. All the evidence on hand, both in nature and in the laboratory, points to the fact that life only ever comes from life. The Bible credits the origin of life to the power and design of a 'living' creator God."

Many people are unenthusiastic about their work.
