Did you know ? Tennis balls haven’t always been yellow. At first they were white, like on the picture.
Unfortunately, when television arrived, it was a little complicated to follow the ball on black and white screens. They found out that yellow was easier to see than white on those old screens. Indeed, the contrast between the ball and the ground was higher on every type of court (grass, clay or hardcourts of concrete).
Therefore, in 1972, the International Tennis Federation made it official that tennis balls will be white or yellow. Indeed, you can still play with white ones in official competitions even if yellow ones became the standard.
By the way, if you want to know more about the strict specifications of a tennis ball, it has to have a diameter between 6.35 and 6.67 cm, a weight between 56.70 and 58.45 g and it has to bounce higher than 1.34 m but lower than 1.47 m when dropped at 2.50 m above the ground.
Nous vous en avions parlé la semaine dernière, la compétition de vidéos scientifiques organisée par les enseignants d’anglais s’est déroulée hier midi et trois réalisations se sont vues primées par le jury composé d’élèves et de professeurs !
En troisième position, Morgan CROCIATI et Samuel COURTHIAL, deux élèves en INFO3, nous ont présentés différentes expériences avec des œufs.
En deuxième position, Basten HATINGUAIS et Corentin LOPEZ, respectivement en INFO3 et en IESE3, se sont amusés avec du sable qui semblait presque magique !
Enfin, les grands vainqueurs du jour sont Félix AUGEARD et Jean-Victor AUTRAN, deux étudiants de troisième année en IESE, qui nous ont appris à faire de la « glace chaude instantanée » à partir d’acétate de sodium. Une expérience vraiment impressionnante !
Nous félicitons évidemment tous les participants, et espérons vous retrouver l’année prochaine pour de nouvelles vidéos toujours plus passionnantes !
Derry Girls is a miniseries directed by Lisa McGee that is constituted of six 25-minute long episodes.
It deals with the lives of a group of teenagers in a 1990s conflicted Northern Ireland.
The show is not only brilliant and entertaining, it also reminds you of Northern Ireland’s history. Having the ripples of the Troubles impact on the lives of European teenagers and seeing the adjustments needed to handle the tension is quite striking, especially if one forgot that it happened not so long ago.
Apart from that, the show casts real Irish actors and you get to appreciate proper Irish accents. You may learn new idioms as well, some you would never hear in a Hollywood movie, such as the renowned « Catch yerself one! » and the overused adjective « wee ».
It may be a short series but don’t hesitate to check it out, it is really worth it and currently available on Netflix France!
An internship is a valued feature in one’s resume that one can readily use to prove they have a keen familiarity with the workplace environment. In consequence, it is essential for every student to find one, and, unless you tend to be a very obnoxious person like those people who eat tangerines in public places, there should be no reason for you to get none.
Following here are the steps to get an internship:
1. Rely on your wondrous assets and mesmerizing skills to charm your potential employers – in other words: Piston, piston, piston!
2. Master some foreign languages for any internship that will take place abroad and learn to translate: « J’aimerais être pistonné, s’il vous plaît. » : « I would appreciate it if you would pull a few strings for me, please. »
3. Target the companies which solutions and outlook on the world motivate you – aka the behemoths that pay well. (Don’t forget about the overlooked ones like Orange or the SNCF!)
4. Finally, polish your resume and cover letter (but you won’t need it if the strings were properly pulled).
You now have all the requisites necessary to get that internship you desire so much. You may relax and wait for the HR departments of all the companies you’ve reached out to to call you back!
And don’t forget how to say « piston »!

Today we meet Olivier Troussard, a student in TIS5 at Polytech Grenoble. He is the captain of the two school’s League of Legends (LoL) first team (out of two).
Who are you?
My first year at Polytech was at Lille in PeiP C after one year of PACES. I participated in a tournament between a couple Polytech schools but I was playing just for fun at the time, so we lost quickly. Then I arrived at Grenoble the next year, in TIS, and I continued playing without taking part in any tournament. It’s only since last year that we put together the first LoL team and participated to our first tournament together. That year I played to Counter Strike, and a member of the team played to LoL (and ranked second!) at a LAN with the INP and the Imag. This year, we continued playing with other Polytech students and participated to a some tournaments. As I am currently following a sandwich course, I travel very often between Paris, where I have my desktop computer, and Grenoble, where I go to the Meltdown bar to play and train. It is not easy but it is worth it, I enjoy playing a lot, even if I do not plan to make it a professional career.
How did the LoL team start?
Last year, a student tournament already took place, to which we participated with the majority of the members of our current team. For this year’s edition, the organisers (the Student Gaming Network association, based in Lyon) improved the overall organisation and offered more interesting prizes (unlike last year, they are supported by Riot France, the makers of the game). So I asked if they wanted to do it again, and they were ok: we have 11 players, enough to create 2 teams of 5 players with 1 substitute player in the first team. We play LoL because we like it (of course), we have enough players with a high enough level and it is the videogame with the biggest tournaments in France.
Is there a difference of level between the teams? Do they practice the same way?
Yes, they are pretty different one from another. The first team is rather high level, the second one is more for fun, they don’t seek to be the absolute best. I am the captain of the first one. Our team do practice a lot at home, even more when a competition is coming soon: 2 to 3 practices a week, during which we do 3 games of approximately 1 hour each, so 6 to 9 hours a week.
What level are your players and do you help each other? (see Figure 1)
In the first team, we have one Master, one Diamond 3-4 (me), two Diamond 5 and two Platinum 2-5. In the second team they are Gold and Silver. Our Master and I play since 2012, our Diamonds since 2013-2014 and the others started later, hence their lower level. Last year, since we only had one team, Guillaume, Théo and I (Diamond players) gave some advice to two other Silver players so that the level would be sort of uniform. This year we don’t have many interactions between the two teams, even though the second one watches most of our games.
« Leagues are groups of players of similar skill level, and there are many leagues in each tier. [Players have to] win ranked games to be promoted to a league of the next tiers. All leagues (except those in the Master or Challenger tier) are broken down into five divisions: 1 is the highest and 5 the lowest. [It] shows the progress toward a league in the next tier. »

How do you prepare for a tournament and do you have predefined roles?
We watch our opponents games, as a team but also each player individually in games where they don’t play with their team: every champion they usually play, their stats… All of the information is summarized in a big Excel sheet. We also think of which champions we will choose in consequence. There is a lot of upsteam work. We change our substitute player regularly so that everyone can play and not only the ones with the highest level. When a player is the substitute, he has an analist or coach role.
Do you have any sponsors and what can you win?
No, and this is not something we are looking for, we are not a pro or semi-pro team where results are expected. There are approximately 600 french teams and even if we are theorically the 12th team on a national level (based on our players individual levels) sponsors are only interested in the teams in the top 3 I would say. We can win for example Riot points (the game’s currency to buy champions, skins, etc.), a book with some artworks of the game or even a Monster fridge, filled with the brand’s cans.
How was your past tournaments and do you have any others planned?
At the beginning of the year we lost in quarter-final. We have played our second tournament with 128 teams so 8 games for each team: we have won against, INP, Phelma and University Paris Créteil amongst others. We ranked 24th in France! It will probably be our last tournament this year, since most of our players are in fourth year and that many of them will go abroad for their internship, which will make the organisation way more complicated, but we’ll see. We are informed of the upcoming events through the official Student Gaming Network Discord server (https://discordapp.com/invite/sgnw). Next time we will have a tournament or a game streamed live it will be shared on the BDJ’s Facebook page and on the school’s Discord.
