Nothing can keep tech stocks down as Apple and Amazon shine

A big week for Apple and Amazon is buoying tech stocks, pushing the Nasdaq Composite back to the lofty levels it reached in late August. That may raise eyebrows, but good luck finding true skeptics.

What Is Mars Opposition? How, When And Where To Watch Red Planet Shine Bright

KEY POINTS

  • Mars will be in opposition Oct. 13
  • A planet is in opposition when it aligns with the Earth and the Sun
  • Viewers can watch the event through Virtual Telescope Project’s Mars opposition viewing

Viewers can observe the Mars opposition Oct. 13 where the planet can be seen in the night sky.

Now that we’ve seen Mars hit its closest approach to Earth on Oct. 6, we can now expect to see it beaming in the night sky this Tuesday, when it will align with Earth and the Sun, giving viewers from Earth the closest view they can get for the next 15 years. The next time we’ll see Mars this close will be in 2035, according to an article by Space.com.

Mars and Earth, as well as all the other planets in the solar system, orbit the Sun at different distances and speeds. But every two years or

How things deform and break is important for engineers, as it helps them choose and design what materials they’re going to use for building things. Researchers at Aalto University and Tampere University have stretched metal alloy samples to their breaking point and filmed it using ultra-fast cameras to study what happens. Their discoveries have the potential to open up a whole new line of research in the study of materials deformation.


When materials get stretched a bit, they expand, and when the stretching stops, they return to their original size. However, if a material gets stretched a lot, they no longer return back to their original size. This over-stretching is referred to as ‘plastic’ deformation. Materials that have begun to be plastically deformed behave differently when they’re stretched even more, and eventually snap
