Physicists have experimentally reversed electromagnetic waves in time, confirming a theoretical prediction that has stood for decades. The process, known as time reflection, causes a wave to retrace ...

Why do we call it the “American experiment?" This phrase captures the tentative, evolving nature of our democracy, reminding us that what we have built is not guaranteed but continually tested. The ...

In the heart of the nation's capital, in a courthouse of the U.S. government, one man will stop at nothing to keep his honor, and one will stop at nothing to find the truth.

ChatGPT, the newest chatbot from OpenAI, has been making waves since its introduction in November 2022. Within a month of its launch, it has already reached a growth rate exceeding millions of active ...

The shot gathers of the Finnish Reflection Experiment 2001–2003 are also available as SEG-Y files with field static corrections applied. For the time being, these files are only available in the ...

Seismic reflection profiling is used for making 2-D or 3-D cross-sections of underground structures. The principle behind reflection seismics is the same as with underwater echo-ranging. A typical ...

Explores the principles of light, reflection, and magnification through hands-on experiments. Children observe how a magnifying glass focuses sunlight to create heat, examine the effects of light on ...

Researchers have seen Klein tunnelling – a rare relativistic phenomenon in which a tunnel barrier disappears – in a topological superconducting state for the first time. The result sheds more light on ...
