Saint Patrick’s Day is a cultural and religious celebration occurring annually on 17 March. The day commemorates Saint Patrick and the arrival of Christianity in Ireland, as well as celebrating the heritage and culture of the Irish in general. Celebrations generally involve public parades and festivals, céilithe, and the wearing of green attire or shamrocks. Christians also attend church services, and the Lenten restrictions on eating and drinking alcohol are lifted for the day, which has encouraged and propagated the holiday’s tradition of alcohol consumption.

“There are some hundred billion (1011) galaxies, each with, on the average, a hundred billion stars. In all the galaxies, there are perhaps as many planets as stars, 1011 x 1011 = 1022, ten billion trillion. In the face of such overpowering numbers, what is the likelihood that only one ordinary star, the Sun, is accompanied by an inhabited planet? Why should we, tucked away in some forgotten corner of the Cosmos, be so fortunate? To me, it seems far more likely that the universe is brimming over with life. But we humans do not yet know. We are just beginning our explorations. The only planet we are sure is inhabited is a tiny speck of rock and metal, shining feebly by reflected sunlight, and at this distance utterly lost.” — Carl Sagan
A car is a wheeled, self-powered motor vehicle used for transportation.

“The development of full artificial intelligence could spell the end of the human race.” — Stephen Hawking
“I think we should be very careful about artificial intelligence. If I had to guess at what our biggest existential threat is, it’s probably that. So we need to be very careful.” — Elon Musk
“I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage it well. A few decades after that though the intelligence is strong enough to be a concern. I agree with Elon Musk and some others on this and don’t understand why some people are not concerned.” — Bill Gates
