[Question] [ How would you design armour to be effective against wizards? For simplicity's sake we'll have the only magic available to the wizards be elemental magic(fire, ice, electricity, wind, light), and they have to cast it as a bolt or stream from a wand or staff, where the wand can be fired off in quick succes...
[Question] [ Imagine both humans uploaded into computer networks and biological humans exist in the same society.

Because th...

[Question] [ Usually "space battle" posts want to achieve some particular fantasy aim (like, realistic where fighters still exists), or they are focused on aliens and whatnot.

[Question] [ Suppose, for instance, you lived in a world filled with nasty monsters and other creatures of the night, all of whom wanted to kill you and eat you in various ways.

[Question] [ In my world a space civilization is colonizing a massive solid planet. The planet has an extraordinarily fast rotation.

[Question] [ I had a thought last night about how to build a more efficient furnace in a fairly low tech society.

[Question] [ I just thought of something.
