  10. 1911 Mistake in the first calculation of the bending of light
  11. 1913 Mistake in the first attempt at a theory of general relativity
  12. 1914 Mistake in the fifth proof of E = mc2
  13. 1915 Mistake in the Einstein-de Haas experiment
  14. 1915 Mistakes in several attempts at theories of general relativity
  15. 1916 Mistake in the interpretation of Mach’s principle
  16. 1917 Mistake in the introduction of the cosmological constant (the “biggest blunder”)
  17. 1919 Mistakes in two attempts to modify general relativity
  18. 1925 Mistakes and more mistakes in the attempts to formulate a unified theory
  19. 1927 Mistakes in discussions with Bohr on quantum uncertainties
  20. 1933 Mistakes in interpretation of quantum mechanics (Does God play dice?)
  21. 1934 Mistake in the sixth proof of E = mc2
  22. 1939 Mistake in the interpretation of the Schwarzschild singularity and gravitational collapse (the “black hole”)

From Einstein’s Mistakes: The Human Failings of Genius

Relativity

Einstein theorized that time wasn’t constant — that it was effected by both relativistic frames of motion (velocity) and gravity.

Now scientists at the National Institute of Standards and Technology in Boulder, Colorado, US have measured variances in  with unprecedented accuracy.

I seriously doubt we’re any closer to The Time Machine HG Wells envisioned and certainly the proof probably won’t meet with as much skepticism as On the Origin of Species by Charles Darwin.

Legalizing Pot

A government report this past week showed that illegal drug use was up… and immediately the media latches on blaming medical marijuana as being the cause.

Hello… it’s a down economy; and when the economy is bad, and people are out of work, drug use typically increases.

I’m not entirely sure that marijuana should be legalized; I’m more for supporting federal initiatives that require access to alcohol and tobacco to require a doctor’s prescription and making them available only at regulated dispensaries.

After all, the government knew years ago that both tobacco and alcohol were far worse than marijuana… and if there’s any gateway drugs we should be concerned with it’s alcohol and tobacco — after all, I’m willing to bet that an incredibly large number of illegal drug users use or used alcohol and/or tobacco first.

Get a grip America — the double standard in dealing with “harmful” substances is part of the problem… and guess what, prohibition failed (miserably); just read what wealthiest supporters of prohibition said after it was repealed:

When Prohibition was introduced, I hoped that it would be widely supported by public opinion and the day would soon come when the evil effects of alcohol would be recognized. I have slowly and reluctantly come to believe that this has not been the result. Instead, drinking has generally increased; the speakeasy has replaced the saloon; a vast army of lawbreakers has appeared; many of our best citizens have openly ignored Prohibition; respect for the law has been greatly lessened; and crime has increased to a level never seen before.

High Speed Rail might be de-railed

It’s very likely that one of the casualties of the mid-term elections will be the high-speed-rail grants.

Representative John Mica (R-FL) who is in line to be chairman of the House Committee on Transportation and Infrastructure has indicated he wants to re-examine all $10 billion worth of high-speed-rail grants that have already been awarded around the country.

High speed rail service would be an extremely cost effective competitor to increasing air transportation; it would be far more eco-friendly; use less energy; potentially use renewable energy; and unlike airports, high speed rail stations could be in the middle of busy metropolitan areas.

No question the US has to tighten it’s belt and bring it’s spending in line with it’s bank accounts — but investments in long term infrastructure improvements are likely what will allow the economy to rebound and gain a solid footing.

I’d say we need to look at all the spending and make sure we make cuts where it’s waste first — and then weigh the costs and benefits before making other cuts.

As I’ve posted before — we could cut down the salaries, retirement pensions, and health insurance costs for elected official… that’s a good start to savings — and elected officials should get the same “benefits” they approve for the American people.

The Incredible Shrinking State

Rising Temperatures, Disappearing Coastlines
December 8, 2009

Greenland and Antarctica hold the world’s largest reservoirs of fresh water, locked in their giant ice sheets. Global warming may cause large parts of these ices sheets to melt within centuries — changing the shape of coastlines around the world.

US Drug Policy

I certainly don’t have a solution to the drug problem in the US; but clearly the US government doesn’t either.

History teaches us many lessons, and when we ignore those lessons we often find ourselves repeating the errors of the past.

Prohibition didn’t work.

We make arbitrary decisions about which drugs are acceptable are which ones are not (we have legalized alcohol, but not drug in social use for much longer).

The Criminal Justice Policy Foundation has some interesting views on US drug policy:

The United States is at a crossroads in its drug policy. In our effort to quell the drug trade, we have greatly increased patrol and inspection on our nation’s borders. We have increased arrests for violation of drug laws and lengthened sentences. We have stripped away the rights of drug offenders and introduced drug testing in our nation’s schools and workplaces. We have poured billions of dollars into overseas anti-drug paramilitary operations that commit violent human rights abuses. And in the process of trying to eradicate illicit coca crops, we have destroyed over a million acres of land in Colombia alone.

Since 1990, more than half of the federal prisoners in America are serving time for drug offenses. The availability and purity of drugs has steadily increased over the past twenty-five years. The violence in the drug trade remains excruciatingly high and surges from year to year and city to city. Meanwhile, there remain a myriad of social issues as a result of drug abuse.

The use of drugs, and the enforcement of the anti-drug laws, effects all subpopulations in the U.S., all sectors of the economy, and many aspects of the legal system. Whether we are talking about violence, poverty, race, health, education, community development, the environment, civil liberties or terrorism, the illegal drug market is an important factor in the conversation.

We have tried to use force, prohibition and incarceration to control the drug market, but our efforts have actually led to a more efficient drug trade and a hugely profitable drug market. It is time to rethink our strategy and redefine our goals.

This section holds articles and speeches given by CJPF that address drug policy in all of its forms and effects. In this, we strive to provide a comprehensive framework for rethinking the war on drugs.

And if you’re wondering, I found their site through an article from NPR on taxing cocaine rather than (or in addition to) marijuana.

Deficit Spending – RNC Style

These are the people who were elected to put the nation’s economy back on track?

Washington (CNN) – The Republican National Committee raised $5.2 million last month, but still is saddled with a debt of more than $21 million from the 2010 midterm elections.

The RNC was able to pay $1 million toward reducing the debt in February, but received an additional $1 million in invoices from 2010 that left its financial position virtually unchanged, according to a report that will be filed this afternoon with the Federal Election Commission. CNN was provided the data prior to the filing.

BANG!

In the Summer of ’62 the US military detonated a hydrogen bomb in outer space above the Pacific Ocean as part of a project code named: Starfish Prime.

There’s a good article on NPR you can read at:
