Review first posted at

In the year 2055 (about 100 years in the future when Ray Bradbury wrote this classic science fiction short story), one of the uses of time travel is for big game “safari” hunting: hunters pay a huge fee to take a guided safari trip to the far-distant past and bag a Tyrannosaurus Rex or other dinosaur. In order to avoid any chance of changing the past and affecting the future, the hunting party is strictly enjoined to stay on a metal pathway floati

The butterfly effect is a term coined by Edward Lorenz, an American mathematician, meteorologist, and a pioneer of chaos theory (and who does NOT look like Jeff Goldblum) that essentially says that a hurricane can be influenced by the distant flapping of butterfly wings several weeks earlier. Although his research took place in the 50s, his description of the idea took place in the later 60s.

Ray Bradbury’s short story A Sound of Thunder, first published in Collier's magazine in the June 28, 1952
Butterfly Effect, Chaos Theory, time paradoxes, all are contained in this brilliant short story by Ray Bradbury. It's about time travel and it's possible consequences on the future, and as usual Bradbury's messages are not delivered with subtlety; they are delivered with force and they are delivered loudly, and they roll around in your consciousness like "a sound of thunder".

What would happen if you make the tiniest of errors?
Bradbury makes a great explanation of the chaos theory. Contrary to popular belief, he did not invent the concept of the butterfly effect.

One of the most interesting short stories I've ever read.
Short Story

Excellent story - Bradbury is the first person who showed "The Butterfly Effect" in this story from the 1950's. Definitely want to read more of this author.

I was tutoring my student for the final exam, and she had to revise this short story while I was there, sitting calmly to contain the envy.
Everyone should read this classic Bradbury short story. Why? So you know the origin of the term "The Butterfly Effect," of course. Bradbury is amazing. Even if sci-fi isn't your normal fare, you can give up 15 minutes of your life to read this classic tale.

Probably my most favourite short story that I've ever read! Also the first by Ray Bradbury. I definitely will be looking out for more of his novels/short stories. I actually read this twice through I enjoyed it that much!

A creepy short story of a time travel trip gone wrong. Intelligently portrays Butterfly Effect and it's implications.

About the Book

This story features a time safari that takes you back in time to hunt dinosaurs – and warns of the danger of altering the past.

Why did I choose this book to read?

I was reading The Egg and it reminded me of how much I loved this story when I was back in Year Eight, and my partner and I had been discussing the theory behind this a
Fun, easy read for school.

Personal Response:
Honesty, this short story wasn't all that great. It didn't really make sense at times and I found it to be pretty boring. Now to some people it was good, but it just wasn't very good to me. This is probably not a book that I could go back to and read.

This story starts out with the main character, Eckels, handing over ten thousand dollars to go on a safari hunt. Now this isn't any ordinary safari hunt, it was a hunt for dinosaurs. At the place where the safari was at, th

Adorei, adorei, adorei! 5 estrelas! Tema e assuntos abordados muito interessantes. Gostei muito da organização do texto e da forma como a viagem no tempo foi abordada. Vale muito a pena ler!

Plot summary: In this story the plot is about a man named Eckels who wants to go back in time to hunt the biggest game of all time, a Tyrannosaurs Rex. In the story Eckels has to pay a fee of $10,000 and has to follow every instruction that the safari guide gives him. He is told not to step off of the path they have made as it could alter many things in the future. After seeing what he got himself into Eckels realizes he is in over his head and says he wants to head home, but when the dinosaur s ...more
Excellent short story, definitely Ray Bradbury was a better short stories writer, at least I've liked better all the short stories that I've read.
This one is about time travel and the consequences a small change in the past can have on the future. It's very short but it raises all the right questions and makes you wonder what will happen next. I really recommend it especially if you like time travel stories. There's a movie based on this, you can watch it but it's awful.

Esta es una excelente his

This is actually a short story from Ray Bradbury. Its not something super shiny or fancy by today's standards, but there are so many books, comics and movies that have been based on the things written in this story. At its core, this book is about rich men who manage to pay for a unique experience. They get to enter a time machine and go back millions of years to hunt dinosaurs. This does not go well for them, and the mistake, literally the Butterfly Effect used more and more ever since this sho ...more

I had to read this for my English class. I wasn't really expecting much because the stories we had read earlier in the year were pretty boring. She put on the recording of some guy reading it (I personally hate those, because when I read it later, I hear the voice) and handed out the story. I tuned out the recording and her constant stops to explain words (Ugh!) and just read it. I was surprised by how much I really enjoyed it. Even kids who hated reading (Basically my entire class) liked this. ...more

The short story "The Sound of Thunder" is one of my favorite short stories. I find it very intresting, and not boring at all. There are things happening all through the story. There isn't a part that you just want to skip because its taking too long for something intresting to happen. It's a story about time traveling, and how it can change everything just if you mess one little thing up. I don't think many people realize how something so small could change a lot. And that's why I think this sto ...more
