  • Let me introduce you to Mr Newton. Specifically:

    F = m*a

    To accelerate on a flat terrain (nevermind a slope) you need to apply tractive force proportional to your mass. Water does add a lot of mass.

  • Elon Musk Bought Twitter to Settle His Jet-Tracking Beef, New Book Claims
  • He could had pulled out of the bid as well me thinks. Between presenting a bid and closing the deal there should be **due diligence **.

    This is what I understand Mr Musk failed to do, after that it would have been nearly impt to cancel the deal.

  • Physicists Designed an Experiment to Turn Light Into Matter
  • Abstract:

    We discovered a simple regime where a near-critical plasma irradiated by a laser of experimentally available intensity can self-organize to produce positrons and accelerate them to ultrarelativistic energies. The laser pulse piles up electrons at its leading edge, producing a strong longitudinal plasma electric field. The field creates a moving gamma-ray collider that generates positrons via the linear Breit-Wheeler process—annihilation of two gamma rays into an electron-positron pair. At the same time, the plasma field, rather than the laser, serves as an accelerator for the positrons. The discovery of positron acceleration was enabled by a first-of-its-kind kinetic simulation that generates pairs via photon-photon collisions. Using available laser intensities of 1022  W/cm2, the discovered regime can generate a GeV positron beam with a divergence angle of around 10° and a total charge of 0.1 pC. The result paves the way to experimental observation of the linear Breit-Wheeler process and to applications requiring positron beams.
