Unpredictable sisters: maths, physics and astronomy

The ninth panel of the Lower Silesian Science Festival is entirely devoted to sciences. It comprises three categories: Mathematical Kaleidoscope, Physical Spectrumand On the Way to Stars. In order to convince the unconvinced that science can be fascinating, we have prepared a host of interesting lectures, revelatory laboratories and breathtaking displays.

 

Mathematical Kaleidoscope

Mathematical Marathon

The Mathematical Marathon is one of the most thrilling competitions set up by the LSSF. The qualifying test lasts for 45 minutes and results are given 15 minutes after the end of the test. The results are also published in the afternoon on the same day at http://fmw.uni.wroc.pl.

The qualifying test is held on 21stSeptember for Wrocław schools and on 22ndSeptember for schools outside Wrocław. The finale takes part on 23rdSeptember and consists in writing consecutive rounds for 40 minutes at full hours. During each round, participants with the lowest results drop out of the competition. Contestants who finish the marathon after 10 in the evening must be picked up by their adult guardian. Contestants who spend 10 hours in the marathon are provided with refreshments and those who finish after midnight are given a place for sleeping at the Mathematical Institute (please take your sleeping pads and bags).

 

Mathematician at the casino

Counting cards at the casino is illegal. However, is there anyone who would like to acquire that skill? During the lecture, an audience will get to know a strategy, during which it is possible to win a small sum of money. Prof. Buraczewski will talk about the students from the Massachusetts Institute of Technology, who won 8 mln dollars in the lottery. The goal of the lecture is to explain the law of large numbers. Don’t hesitate to participate. It could be rammed.

 

Mathematician-humanist

The humanist seeks the truth. The humanist rules out egoism. For the humanist man is the centre of attention. So why do we differentiate the sciences from the humanities? Do they contradict each other? Why did Hans Freudenthal say that among the humanities mathematics is the most humanistic? All answers to these questions will be given at the lecture, where a lecturer tries to explain why being a mathematician has been the best profession in the world for years.

 

Physical spectrum

Physics of water – amazing properties of water

We have contact with water every day. Water constitutes as much as 70% of the body weight. It seems that we know everything about water. Meanwhile, water is one of the most mysterious chemical substances on Earth. What is its biological significance and why do we owe it our lives? Is water present only on our planet? Water is a liquid  behaving in an unusual way, which will be explained at the time of the lecture. Additionally, participants will learn about why water has a very high boiling point and why warm water freezes faster in some conditions despite its small molecular mass. Do you think it’s possible that water can simultaneously boil and freeze? It’s worth coming and garnering some information, seeing that we are virtually water.

How to grow a crystal?

Everyone has heard about solid bodies and crystals. However, what they are isn’t so obvious. A lecturer will explain the difference between these two condensed states; how to differentiate a solid body from a crystal; and why we say that a crystal can be grown but not received. Crystals have many secrets to be revealed.

 

On the Way to Stars

Light of a star is like “DNA”

In order to specify some properties of living organisms, biologists investigate DNA, which creates genes. But what can astrologists do? After all, they probe objects that are hundreds and even billions of light years away from Earth – places we never reach as humans and from which we never take any samples. The answer for astronomers is a light which constitutes the DNA of a distant star, galaxy and planet. The aim of the workshop is to account for the ways scientists indicate stars’, galaxies’ and planets’ temperature, distance, and even their chemical structure. The spectroscope with three spectrums present in nature will be displayed. After the classes, participants will have a chance to observe the sun under the telescope (weather permitting).  

Everyone – even those still unconvinced that each mathematician is at the same time a humanist – is invited to take part in panel entitled “Mathematics, physics, astronomy – three sisters.” We can promise you won’t squander your time.
