This image may not be used in educational posters Double-slit experiment Computer illustration showing a plane wave (bottom right) passing through a gap in a screen, and the resultant circular wave then passing through a screen with two gaps. The gaps act as new wave sources and the wavefronts bend to create two sets of circular waves radiating outwards. These two new waves create an interference pattern as they interact. At the point where a wave peak from one hits a wave peak from another, or a trough hits a trough, they reinforce each other; their magnitudes are summed. This is known as constructive interference. Where a trough hits a peak or vice versa and they cancel each other out. This is known as destructive interference.

Can particles really be in two places at the same time?

When talking about quantum physics, people will often nonchalantly say that particles can be in two places at once. Physicist Sabine Hossenfelder explores what is actually going on

SALISBURY, ENGLAND - Challenger 2 Main Battle Tank during a training exercise on Salisbury Plain Training Area in Salisbury, England. 5 RIFLES Battlegroup prepares for deployment on Op CABRIT in Estonia as part of the NATO enhanced Forward Presence later this year. 5 RIFLES Battlegroup is trialing a new concept of training or Operational Readiness Model (ORM) on behalf of The Field Army to ensure they are mission ready. Additionally, due to the Coronavirus pandemic, training methods have been adjusted with innovative measures introduced to ensure that training isn't compromised and expectations and operational outputs lowered.
