#Clarke's three laws

• When a distinguished but elderly #scientist 👨‍🔬 states that something is #possible, they are almost certainly right. When they state that something is #impossible, they are very probably #wrong.
• The only way of discovering the #limits of the #possible is to venture a little way past them into the #impossible.
• Any sufficiently #advanced #technology is indistinguishable from #magic.
