NASA’s double-asteroid redirection test, launched in 2022, was an actual experiment in space. It sent a rocket to strike an ...

What did Newton understand that was such a revolution? Can someone just... explain gravity to me? Let's start with a ...

Atomic force microscopy (AFM), a form of scanning probe microscopy, is a technique where a cantilever with a sharp tip is systematically scanned across a sample (biological or material) surface to ...

“Neither orbits nor radio waves obey international boundaries,” University of Colorado engineering professor Al Gasiewski said. While “international cooperation” on a roadmap for space conduct is ...

Bohr guessed that the everyday laws of physics do not apply in the ultra-small realm of the atom. He remembered the quantum. Maybe only certain orbits with discrete energies were allowed. He had no ...

We investigate the over-barrier ionization of hydrogen atoms in intense circularly and elliptically polarized laser fields. By solving the time-dependent Schrödinger equation, we simulate the ...

Sir Ernest Rutherford has been called the 'father of nuclear physics' When Donald Trump claimed US scientists split the atom in his inaugural speech, even he could not have imagined the chain ...

When Donald Trump claimed US scientists split the atom in his inaugural speech, even he could not have imagined the chain reaction of online debate his boast would cause. Many of those leaping on ...

Using lasers, they then boosted the atoms' outermost electrons to very high orbits, making the atoms approximately ... is far away from the core of the atom, making it more responsive to electric ...
