Minecraft: Magnetic Travel Puzzle

Review

Minecraft: Magnetic Travel Puzzle (M:MTP for short) is a travel game by ThinkFun in which the goal is to arrange 3 types of objects, each coming in 3 different colors, in a 3 by 3 grid, such that certain conditions are satisfied.

As you progress through the 40 included challenges, the types of conditions you encounter become gradually more complex. While in the beginning you may be given all the colors of the objects with one clue and all the types of the objects with another, later on you need to analyze 5 or 6 clues at once, which makes the game more challenging and fun. That being said, at the hardest levels, M:MTP is still relatively easy, so experienced puzzlers will probably breeze through it within an hour or two.

At its core, M:MTP is identical to ThinkFun’s previously released Clue Master. Both games are presented in the form of magnetic notebooks, so they are easy to pick up and travel around with. The illustrations of the Minecraft edition are all based on the popular video game, so its fans may be particularly appreciative.

If you are looking for a casual puzzle to pass an hour or two on a road trip, then M:MTP would be a great choice. I only wish there were more challenges included, especially more difficult ones.

  • 1 player, 8 years and up
  • 40 challenges with increasing difficulties
  • easy to transport and play on the go
  • cool Minecraft based art
  • most puzzles can be solved with a few simple techniques

Cat Crimes

Review

Cat Crimes is a logic game by ThinkFun inspired by classic deduction puzzles. It consists of 40 challenges split into four difficulty groups.

Each challenge presents the player with a cat crime which they must solve. One of six items on a carpet has been ruined, and several clues written on a card point towards the cat which is responsible. The player must analyze each of the clues, as well as the models of the cats and the carpet (included in the box), and find the perpetrator. Even though the puzzles can be completed just as easily with pen and paper only, the inclusion of cardboard models makes the solving process much more fun. The beautiful artwork of the set and the sturdy cardboard additionally improve the experience.

The included puzzles are best suited for students in primary and middle schools, but older people can enjoy them as well. Overall, Cat Crimes is a wonderful twist on a traditional type of puzzle, and I highly recommend it.

  • 1 player, 8 years and up
  • 40 challenges, 4 difficulty levels
  • a fun variation of a classic deduction puzzle
  • beautiful models of cats and carpet

Manifold: The Origami Mind Bender

Review

In an age of video games and noisy high-tech toys, Brainwright’s Manifold is a rare find. I got truly delighted by the idea of folding little papers into origami, trying to achieve some easy-to-understand task. The goal is simple – you start with an 8×8 paper which has 16 black, 16 white, and 32 empty squares printed on its front. You must make several folds so that the paper ends up as a 4×4 piece with all black squares on one side and all white squares on the other.

For just about $10 I was able to get a set of 100 puzzles, which translates into several hours of gameplay. The difficulty of the puzzles gradually increases, which makes Manifold appropriate for all ages. Despite my highly positive impressions, I have to point out several (minor) flaws. First, the glossy paper, despite its high quality, may not be the best choice for making origami. Second, there is too much space left at the edges of the papers, which may get in the way when one needs to make many folds in one puzzle. Finally, since the creases can’t be removed from the paper, it is unlikely that you’ll be able to solve the puzzles more than once.

If you want to try some sample puzzles from the set before buying it, you can print them from this PAGE.

  • 1 player, 10 years and up
  • 100 challenges, 4 difficulty levels
  • origami-based puzzles
  • many hours of gameplay
  • the glossy paper makes it hard to fold
  • puzzles are likely to be discarded after solved

Physics Jokes

Who says science jokes are not funny? Below you can see some of the best Physics jokes we know, along with short explanations of the more obscure of them.

Do you know any funny Physics jokes yourself? Let us know in the comment section below.


“Where does bad light end up?”
“In prism.”

Explanation
A word-play with the word “prison”.


“Why does a burger have less energy than a steak?
Because it is in its ground state.”

Explanation
The ground state of a mechanical system has the least possible energy.


Einstein developed a theory about space. And it was about time too.

Explanation
The joke is a wordplay with the fact that Einstein developed a theory about space-time relativity.


“Theory is when you know everything, but nothing works. Practice is when everything works, but no one knows why. In our lab theory and practice are combined – nothing works and no one knows why.”


“What is a physicist’s favorite food?”
“Fission chips.”

Explanation
Fission chips” sounds like “fish’n’chips“. Fission is a radio-active process during which a nucleus splits into two or more nuclei.


Two theoretical physicists are lost at the top of a mountain. Theoretical physicist No 1 pulls out a map and peruses it for a while. Then he turns to theoretical physicist No 2 and says:
“Hey, I’ve figured it out. I know where we are.”
“Where are we then?”
“Do you see that mountain over there?”
“Yes.”
“Well… That’s where we are!”

Explanation
Theoretical physicists are regarded to be very detached from reality.


I have a new theory on inertia, but it doesn’t seem to be gaining momentum.

Explanation
Inertia and momentum are related to the motions of solid bodies.


“How did Einstein begin his stories?”
“Once upon a space-time…”

Explanation
The space-time is a mathematical model of the universe introduced by Albert Einstein.


Yesterday I was reading a book on anti-gravity. Couldn’t put it down.

Explanation
Anti-gravity is the concept of having a place or object which is free from the force of gravity.


A cop pulls Heisenberg and asks him:
“Do you know how fast you were driving?”
Heisenberg replies:
“No, but I know where I am.”

Explanation
Heisenberg’s uncertainty principle in quantum mechanics states that you can not know with certainty both the position and the momentum of a particle.


My friend Power has been very stressed all week. His boss keeps making him work over time.

Explanation
A word play with the formula:
POWER = WORK / TIME


One day, Einstein, Newton and Pascal met up and decided to play a game of hide and seek. Einstein volunteered to be “It”. As Einstein counted to 100, eyes closed, Pascal ran away and hid. Newton however stood right in front of Einstein and drew a 1 meter by 1 meter square around himself. When Einstein opened his eyes, he immediately saw Newton and said, “I found you Newton,” but Newton replied, “Nope, you found one Newton per square meter, that’s Pascal!”

Explanation
A word play with the formula:
1 PASCAL = 1 NEWTON / 1 SQUARE METER


A photon checks into a hotel. The bellhop asks, “Can I help you with your luggage?” The photon replies, “I don’t have any, I’m traveling light.”

Explanation
Photons are traveling light particles.


A student riding in a train looks up and sees Einstein sitting next to him. Excited he asks, “Excuse me, Professor, does Boston stop at this train?” 

Explanation
Physical observations depend on the point of view of the observer.


Why is electricity so dangerous? Because it doesn’t know how to conduct itself properly.

Explanation
Electricity is formed by conduction of electrons in a wire.


A male magnet says to a female magnet:
“From your backside, I thought you were repulsive. After seeing you from the front however, I find you rather attractive.”

Explanation
Depending on the way you connect magnets, they could either repulse or attract each other.


Schrodinger’s cat walks into a bar. And doesn’t.

Explanation
Schrodinger’s cat is a thought experiment related to the theory that a system can be in multiple states until interacts with the outside world. The classic setup is with a cat closed in a box with radioactive substance in it, which could potentially kill her. Before you open the box, the cat is supposedly both dead and alive.


The dean addresses the physics department:
“Why do I always have to give you so much money – for laboratories and expensive equipment and stuff? Why couldn’t you be like the mathematics department – all they need is money for pencils, paper, and waste-paper baskets. Or even better, like the philosophy department – all they need is pencils and paper.”

Explanation
Scientists like physicists and mathematicians consider philosophers to produce mostly useless results and materials.
