My name is Thomas, I am 35 years old and I come from Zurich, Switzerland.
Tennis is my great passion. I constantly seek to improve my play. For several years my goal has been to emulate the Federer forehand. From experience I can tell this is very difficult, but I am getting closer.
Another topic of interest is the very physics of the game. How to achieve an effortless yet powerful swing? How does the racquet itself influence the technique?
Last but not least I am into the learning aspects of the game. The game of tennis is rather difficult to learn. How can we make it easier to pick it up? Are there technical aids that facilitate the learning?
If you have similar interests, do not hesitate to contact me. I am excited to hear your perspective and will share any information I have.

How to win a set: math part

In this post we are going to establish the formula for winning a set given the ability to score a point. We have already derived the formula for winning a game in another post: We will build on that. In fact, winning a set in tennis means winning 6 or 7 games (either 6-any or 7-5)…

Spin calculation

The last post made several claims about topspin production. In this post, we will explore the physics behind them. Recall the illustrative picture of a tennis great from the last post: We can draw the same arrows in a more abstract manner like this: In order to make things easy, we will always draw that picture…

How to increase spin

One of the keys to the modern tennis game is topspin production. In order to hit a heavy ball with consistency, topspin helps to keep the ball in. During its travel through the air, topspin pushes the ball towards the ground due to the Magnus effect. That is why ambitious tennis players seek to increase their topspin…

How to win a game: the math behind

In an earlier post we discussed the probability of winning a game if you know the probability of winning a point. This is the math behind the formula. The complicated part of the calculation is that a game of tennis can go over deuce many times, even indefinitely (in theory, at least). We will therefore treat…

Can You Hold Serve?

Would you like to know how you can hold serve more often? Then, this post is for you. In tennis, with the advantage of the serve you should usually win the point. Not only can you hit the serve without interference from your opponent, you have even got two shots at it! With that much of an advantage, to win the point when…
