René Descartes said the only thing we can be certain about is that we think. But what is the nature of thoughts? Philosophers have pondered this for centuries.

Three groups of cicadas have emerged together this year for the first time since the fall of the Roman Empire. The reason is pure mathematics.
Science philosopher Sam Baron explains where energy comes from on The Conversation’s Curious Kids podcast.
Brain scanners and AI can turn brainwaves into streams of text – but language only captures a tiny fraction of our mental experience.
A new measurement of gravity at small scales hints at an alternative to billion-dollar experiments for the future of physics.
Everybody thinks they know what drugs are, but a clear definition is surprisingly elusive.
It is one thing to treat AI as a tool when it has no scope for emotion. It is quite another when AI has a full suite of emotional responses.
AI models are increasingly being used to make important decision about people’s lives – just take Robodebt. Yet the complexity of these systems means we hardly understand them.
Black holes could take us to the future, and maybe even the past. The hard part would be surviving the trip.
When it comes to physics experiments, quantum simulations aren’t quite the real thing – but in some cases they’re much closer than you’d expect.
The Matter of Everything is a partial account of the history of physics, which leaves out a lot, including the story of some key women scientists.
Ada jenis partikel khusus yang disebut ‘tachyon’ yang harus bergerak lebih cepat dari kecepatan cahaya. Tapi inilah masalahnya – kami tidak dapat membuktikan bahwa tachyon itu ada.
Time dilation might seem like science fiction, but it’s not. There are astronauts circling the Earth right now who are experiencing it – though luckily nowhere near as much as Buzz Lightyear.
Las teorías más avanzadas de la física sugieren que el tiempo puede no ser real, pero incluso si tienen razón, la vida puede seguir como siempre.
There’s a special type of particle called a ‘tachyon’ which would have to travel faster than the speed of light. But here’s the hitch – we can’t prove tachyons even exist.
Teori fisika mutakhir menunjukkan waktu mungkin tidak nyata – tetapi bahkan jika itu benar, hidup masih bisa berjalan seperti biasa.
Cutting-edge theories of physics suggest time may not be real – but even if they’re right, life can still go on as usual.
Energi tidak benar-benar terbuat dari hal lain. Ini semacam kapasitas untuk melakukan sesuatu
Did humans invent mathematics or does it exist independently?
Energy isn’t really made of anything else. It’s a kind of capacity to do things
The idea of an automated weapon system shaped like a dog might make us feel morally queasy. But in truth we should feel just the same about existing military drones that kill people remotely.
The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
Einstein was awarded a Nobel prize for his explanation for how light can be described as being made up of individual particles of energy under certain conditions.
Bending space into warp bubbles to travel faster than light may never be a reality, but distorting the flow of time just might be possible.
A long-sought crack in the Standard Model of particle physics may have been spotted.
