The Science of Time

Hey, I'm Harry. Just another highschool student with a science obssession and a blog. Chemistry, Physics and maths are my mains and with them I hope to study electrical and electronics engineering at the University of Adelaide (did I mention I am Australian!). So yeah feel free to message me anytime if you are curious or just need a friend. Disclosure: I am a highschool student not a PhD

Mathematics is like oxygen. If it is there, you do not notice it. If it would not be there, you realize that you cannot do without.

Me and my mother got tickets to see Prof. Brian Cox live. God yes.

Will the car decide correctly? Hit a pedestrian or potentially harm the driver?Is there a right answer? 
“At some point, a car will be built that will make a decision of whether or not it has to save the passenger or kill the person outside the vehicle,” says Penn Stater Sean Brennan.
“If you hit the pedestrian, they’ll almost certainly be killed. If you swerve to avoid them, the car could go over a cliff and kill the driver.”
Sean challenges his students to think about these types of dilemmas. As future programmers, they’ll need to answer those unsolvable questions before they input decision-making algorithms into consumer vehicles.

Spiral galaxy NGC 4911 in the Coma Cluster
A long-exposure Hubble Space Telescope image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light-years away in the northern constellation Coma Berenices.
The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its centre. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes. The high resolution of Hubble’s cameras, paired with considerably long exposures, made it possible to observe these faint details.
NGC 4911 and other spirals near the centre of the cluster are being transformed by the gravitational tug of their neighbours. In the case of NGC 4911, wispy arcs of the galaxy’s outer spiral arms are being pulled and distorted by forces from a companion galaxy (NGC 4911A), to the upper right. The resultant stripped material will eventually be dispersed throughout the core of the Coma Cluster, where it will fuel the intergalactic populations of stars and star clusters.
