It’s been 19 years since Pixar released Monsters, Inc. with all that CGI hair. Where are my hairy icons? Ones that get all long and knotted as the notifications number goes up.
Why can’t I feel my phone? I found that paper from 2010 (when I was complaining about keyboards) about using precision electrostatics to make artificial textures on touchscreens.
I should be able to run my thumb over my phone while it’s in my pocket and feel bumps for apps that want my attention. Touching an active element should feel rough. A scrollbar should *slip. Imagine the accessibility gains. But honestly I don’t even care if it’s useful: 1.5 billion smartphone screens are manufactured every year. For that number, I expect bells. I expect whistles.
Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
