Should Biologists be Guided by Beauty?

by Jalees Rehman in The Next Regeneration

One key characteristic of a beautiful scientific theory is the simplicity of the underlying concepts. According to Weinberg, Einstein's theory of gravitation is described in fourteen equations whereas Newton's theory can be expressed in three. Despite the appearance of greater complexity in Einstein's theory, Weinberg finds it more beautiful than Newton's theory because the Einsteinian approach rests on one elegant central principle – the equivalence of gravitation and ........

Star Trek Shields For Tanks

by Mark E. Lasbury in The 'Scope

Star Trek deflectors absorbed or deflected energy beams, but would they work against bullets or asteroids? Scientists are on working on armors and plasma systems that can stop projectiles. In some cases we use explosions to stop explosions. In others, tanks are turned into electrical pulse generators that zap incoming rockets. But the most amazing is the wall of exploding plasma that will be the first true defensive energy shield.... Read more »

Pulling Us Toward Tractor Beams

by Mark E. Lasbury in The 'Scope

Tractor beams pulling space ships are things of science fiction, but tractor beams pulling small objects on Earth are science fact. Beams usually push things away with their force, but we have learned to manipulate them so that they push things back to the source – we can do it with water, sound and even laser light....

Star Trek Phasers, Coming To Us Sooner or Laser

by Mark E. Lasbury in The 'Scope

Can we make a Star Trek phaser? In a classic example of life imitating art, the militaries of many countries are actively pursuing such directed energy weapons. So far, we’ve developed high-energy lasers and masers, particle beams, and something that looks a lot like an aimed lightning bolt. But our versions are huge, what must be overcome to make hand-held versions?... Read more »

Seeing Our Way to Invisibility

I'll Beam Right Over

by Mark E. Lasbury in The 'Scope

Star Trek’s 50th anniversary is next year. Wouldn’t transporting a person to the ISS be a great way to celebrate? Well, there are a couple of problems to overcome, but we’re on our way. We have recently learned how to transport information and light from one place to another, without it ever existing anywhere in between! And this will help us make quantum computers that will be able to transport all the information contained in every atom of your body.... Read more »

Sometimes Warped Thinking Is A Good Thing

by Mark E. Lasbury in The 'Scope

As Star Trek’s 50th anniversary approaches, are we getting closer to traveling at light speed? Believe it or not – yes, we are. We have begun to understand and harness the power of antimatter, and the plasma bubble-driven warp drive has moved from silly idea to serious consideration – so much so that NASA has designed a warp drive ship, the IXS Enterprise, of course....
