TV Guide has declared the upcoming season the Summer of the Nerd, and we’re faced with many geeky questions: Can a B-list hero like Iron Man carve a niche in a field full of drama queens like Spider-Man and the Caped Crusader? Will the fourth “Indiana Jones” flick suffer the “too little, too late” curse of “Godfather III”? And why would anyone remake “The Hulk” so soon on the heels of the 2003 Ang Lee abomination? Finally, raise your hand if you think the new “X-Files” movie is going to tank as badly as the first one. The truth is out there, but only the most hardcore fans still care.

While you wait for the bulk of the summer blockbusters to hit theaters, whet your nerdy palate with “Star Wars Tech” (7 p.m., History), an exploration of “what-if” technology across the six movies in the franchise, from designing Death Stars to crafting clones. Back in 2005, the BBC reported that a 17-year-old girl and a 20-year-old man in England nearly killed themselves in a mock duel with light-sabers fashioned out of florescent light tubes and petrol. Don’t let this happen to you.

¢ DeAnna Pappas, a rejected contestant on a previous installment of “The Bachelor,” will be pursued by 25 young swains on “The Bachelorette” (8 p.m., ABC). That is all I know, or care to know, or will ever know about this show.
