The Ultimate Weapon

John Wood Campbell

Book Overview: 

The star Mira was unpredictably variable. Sometimes it was blazing, brilliant and hot. Other times it was oddly dim, cool, shedding little warmth on its many planets. Gresth Gkae, leader of the Mirans, was seeking a better star, one to which his "people" could migrate. That star had to be steady, reliable, with a good planetary system. And in his astronomical searching, he found Sol. With hundreds of ships, each larger than whole Terrestrial spaceports, and traveling faster than the speed of light, the Mirans set out to move in to Solar regions and take over. And on Earth there was nothing which would be capable of beating off this incredible armada—until Buck Kendall stumbled upon THE ULTIMATE WEAPON

"The distance is half a light-year now, sir," reported the navigation officer.

"Reduce the speed, then, to normal velocity for these ranges. What reserve of fuel have we?"

"Less than one thousand pounds. We will barely be able to stop. We were too free in the use of our weapons, I fear," replied the Chief Technician.

"Well, what would you? We needed those things in our reports. Besides, we could extract fuel from that ore we took on at Planet Nine of Phahlo. It is merely that I wish speed in the return."

"As we all do. How soon do you believe the Council will proceed against the new system?"

"It will be fully a year, I fear. They must gather the expeditions together, and re-equip the ships. It will be a long time before all will h. . . Read More

I imagine this was a crackerjack tale back in the days of yore. Nowadays it feels incredibly dated and clunky.

The physics are fairly ludicrous, even by 1936 standards, but I will say that I enjoyed the aliens themselves and the explanation of their evolution. I found it interesting that they have tw

This was a highly amusing story because of all the bad science and implausible plot lines. While John Campbell is *the* Editor in Chief of Sci Fi, he kinda flopped on this story. He spent a lot of time discussing the "science" behind all the technology that was designed in the book. That would be fi

The ultimate weapon

This book is in the genre of the early sci-fi books. It is fun to read, entertaining. Great characterization of the hero versus villain.

I approached reading "The Ultimate Weapon" by John Campbell with substantial enthusiasm. Many of my favorite science fiction writers were either hand picked and refined by him, or made their names writing as a reaction to how he shaped the industry.

Sadly, this book leaves me in the latter camp. It's

Definitely dated hard science-fiction. The millionaire scientist is the hero, of course, and humanity wins a war against an alien invader through their ability to overcome the science of the invader. The description of the alien species is unique and the ending (in the epilogue) is not exactly the t
