Eyes on the prize: Why optimists make superb leaders

Recognizing the opportunity the future holds can help you better manage the challenges to come.

  • Effective leadership comes from, in part, an understanding of the challenges the future might hold.
  • Because optimists are able to focus the opportunities the future presents — instead of the impossibilities — they make great leaders.
  • An understanding of science plays a part in more clearly seeing the future, which contributes to better decision-making as a leader.

New study says cosmic acceleration and dark energy don't exist

An Oxford scientist claims a Nobel-Prize-winning conclusion is wrong.

NASA
  • Paper by Oxford University physicist Subir Sarkar and his colleagues challenges how conclusions about cosmic acceleration and dark energy were reached.
  • Physicists who proved cosmic acceleration shared a Nobel Prize.
  • Sarkar used statistical analysis to question key data, but his methodology also has detractors.

  • An astrophysicist and cosmologist Dr. Farnes published a paper while at Oxford University with a novel explanation for dark energy and dark matter.
  • His theory claims to explain the missing 95% of the observable universe by the existence of "dark fluid".
  • This fluid has negative mass, repelling other materials.

Google’s Sycamore beats top supercomputer to achieve ‘quantum supremacy’

The achievement is an important milestone in quantum computing, Google's scientists said.

Google
  • Sycamore is a quantum computer that Google has spent years developing.
  • Like traditional computers, quantum computers produce binary code, but they do so while utilizing unique phenomena of quantum mechanics.
  • It will likely be years before quantum computing has applications in everyday technology, but the recent achievement is an important proof of concept.
