There is No "Up" and "Down"

This flat conceptioning is manifest right up to the present in such every¬ day expressions as "the wide, wide world" and "the four comers of the Earth." As mentioned before, "up" and "down" are the parallel perpendicu¬ lars impinging upon this flat-out world. Only a flat-out world could have a Heaven to which to…

Bush Administration Science Abuses

After President Bush's 2004 reelection, scientists noticed that the problem was becoming even worse. One example was Bush's appointment of George Deutsch, a twenty-four-year-old Texas A&M University dropout and Bush campaign intern, to a key position in NASA's public relations department. Deutsch set to work muzzling…

Newton on the Power of Gravity

As he sat alone in a garden, he [Isaac Newton in 1666, age 24] fell into a speculation on the power of gravity; that as this power is not found sensibly diminished at the remotest distance from the centre of the earth to which we can rise, neither at the tops of the loftiest buildings, nor even on the summits of the…

Relativity

I like relativity and quantum theories because I don't understand them and they make me feel as if space shifted about like a swan that can't settle, refusing to sit still and be measured; and as if the atom were an impulsive thing always changing its mind.

The Case for Robotic Space Exploration

In a dispassionate comparison of the relative values of human and robotic spaceflight, the only surviving motivation for continuing human spaceflight is the ideology of adventure. But only a tiny number of Earth's six billion inhabitants are direct participants. For the rest of us, the adventure is vicarious and akin…

Things Discovered by Many at the Same Time

It is notorious that the same discovery is frequently made simultaneously and quite independently, by different persons. Thus, to speak of only a few cases in late years, the discoveries of photography, of electric telegraphy, and of the planet Neptune through theoretical calculations, have all their rival claimants…

Sarcastic Science

Sarcastic Science, she would like to know, In her complacent ministry of fear, How we propose to get away from here When she has made things so we have to go Or be wiped out. Will she be asked to show Us how by rocket we may hope to steer To some star off there, say, a half light-year Through temperature of absolute…

Human Space Exploration is Overrated

Perhaps what we should do is genetically engineer new forms of Intelligent life that can survive the stress of space yet still conduct scientific experiments. Actually, such creatures have already been made in the lab. They're called robots. You don't have to feed them, they don't need life support, and they won't get…

The Frightening Discovery of the Void in the Atom

When I hear to-day protests against the Bolshevism of modern science and regrets for the old-established order, I am inclined to think that Rutherford, not Einstein, is the real villain of the piece. When we compare the universe as it is now supposed to be with the universe as we had ordinarily preconceived it, the…

The Promotion of the Apollo Program

The success of Apollo was mainly due to the fact that the project was conceived and honestly presented to the public as an international sporting event and not as a contribution to science. The order of priorities in Apollo was accurately reflected by the first item to be unloaded after each landing on the Moon's…

The Enterprise's Impulse Drive

Moving back to the sub-light-speed world: We are not through with Einstein yet. His famous relation between mass and energy, E=mc 2 , which is a consequence of special relativity, presents a further challenge to space travel at impulse speeds. As I have described it in chapter 1, a rocket is a device that propels…

Copernicus on Gravity

I myself consider that gravity is merely a certain natural inclination with which parts are imbued by the architect of all things for gathering themselves together into a unity and completeness by assembling into the form of a globe. It is easy to believe that the Sun, Moon and other luminaries among the wandering…

Surgeons are Like Astronauts

So much goes into doing a transplant operation. All the way from preparing the patient, to procuring the donor. It's like being an astronaut. The astronaut gets all the credit, he gets the trip to the moon, but he had nothing to do with the creation of the rocket, or navigating the ship. He's the privileged one who…

Discoverers Are Not Heroes

Do not expect to be hailed as a hero when you make your great discovery. More likely you will be a ratbag—maybe failed by your examiners. Your statistics, or your observations, or your literature study, or your something else will be patently deficient. Do not doubt that in our enlightened age the really important…

Facts About the Hubble Ultra Deep Field

1.How faint are the farthest objects? The Hubble observations detected objects as faint as 30th magnitude. The faintest objects the human eye can see are at sixth magnitude. Ground-based telescopes also can detect 30th-magnitude objects. Those objects, however, are so dim they are lost in the glare of brighter, nearby…

How Ballooning Changed Our Perspective of the Earth

Ballooning produced a new, and wholly unexpected, vision of the earth. It had been imagined that it would reveal the secrets of the heavens above, but in fact it showed the secrets of the world beneath. The early aeronauts suddenly saw the earth as a giant organism, mysteriously patterned and unfolding, like a living…

We Will Retrieve Pioneer 10

Pioneer 10 is the first interstellar spacecraft launched by mankind. It was also the fastest spacecraft launched, to the date of its departure. But it will take eighty thousand years for Pioneer 10 to reach the distance of the nearest star. Because space is so empty, it will never enter another Solar System. The…

Space Exploration Costs the Same as Exploring the World

The Solar System is much vaster than the Earth, but the speeds of our spacecraft are, of course, much greater than the speeds of the sailing ships of the fifteenth and sixteenth centuries. The spacecraft trip from the Earth to the Moon is faster than was the galleon trip from Spain to the Canary Islands. The voyage…

Sports on Phobos

Because of their small sizes, Phobos and Deimos have very low gravitational accelerations. Their gravities do not pull very hard. The pull on Phobos is only about one one-thousandth of that on Earth. If you can perform a standing high jump of two or three feet on Earth, you could perform a standing high jump of half a…
