Marco Antonio de Dominis was born in 1566 on the island of Rab, Croatia. Prior to attending the Society of Jesus, he enrolled in various education institutions such as university of Padua and the Illyrian college. De Dominis made huge strides in his education rising above the fray to become a leading mathematician. He was simply iconic in everything he ventured in especially in mathematics, theology and science.
Even though his education at Loreto was marked with controversies because of his involvement with the Jesuits, De Dominis overcame his challenges to become a mathematics teacher at Padua and Brescia. His continuous commitment also saw him being employed as a professor of mathematics and rhetoric at Padua and Brescia respectively.
Lots of data can be daunting – how do we know quickly and easily what it all means? Technology is helping us to explore the vast quantities of information we now collect.
There are many technologies to choose from – from the humble graphic calculator or spreadsheet, all the way to inputting data into open source software followed by the use of a 3D modelling suite to create designs. These exciting tools can help you unpack data, knowledge and statistics because of their power and accessibility.
Once statistics have been collected and analysed, a decision must be made on the best way to communicate key messages contained within the data. Often, one or two important pieces of information need to be emphasised. One way to achieve this is through a static visualisation, such as a graph or chart.
A school from Zagreb will be representing Croatia at the international science competition to be held in Turkey. The 22nd edition of the International Research Projects Competition, which is one of the best scientific high school contests in the world, is organised by MEF Educational Institution. The aim of the competition is to attract young science talent and encourage them to be future scientists. The competition gives the students an opportunity to showcase their scientific temperament and ideas by way of working models and projects. The projects may be prepared individually by a student or may be prepared as a group consisting of a maximum of two students and a teacher. The competition is open to all high school students in Turkey and abroad. The competition which will be held from the 7th of May to the 10th of May 2013, will host 120 students from Turkey and another 45 students from international high schools from across the globe.
While many universities, higher institutions of research and other organizations the world over have collectively embarked on the preparations of celebrating 2013 as an important year for the Mathematics of Planet Earth (MPE), scientists from Croatia have come up with a strategic project that will see awareness of such an important year raised efficiently. A group of scientists has taken the task of raising such awareness in four cities across the country. This project aims at raising more awareness and in the end lure the younger population to this important event.
Take a strip of paper and fold it in half end-to-end and make a crease. Open it out and then re-fold to make the crease into a right angle on the inside.
Take a new strip of paper. Fold it in half and then fold it in half again, putting the left end over the right end each time. Open it up, and then adjust each crease to be a right angle.
Take a third strip of paper. Fold it in half three times being careful to put the left end over the right each time. Lie it on its side and adjust the creases to be right angles, as before. Follow this pattern to make a 4- and a 5-fold shape.
Make two 4-fold shapes and see if you can make the 5-fold shape out of them. Can you see a pattern in these shapes?
See if you can make a 6-fold shape by arranging 5-fold shapes.
Does it seem simple to measure the length of a river? Could you grab a tape measure and run it from the start of the river to the end? The trouble with this method is that rivers don’t go in straight lines – they bend.
On flat ground, rivers often curve and form wide bends and loops. All these bends make the river a lot longer than it could be if it followed the most direct path.
If there’s a slight bend in a river, then sand and sediment tends to be deposited on the inside of the curve. Meanwhile, the outside of the bend tends to become eroded. These two actions make small bends into big loops know as meanders.
Andrija Mohorovicic was born in 1857 in Volosca and died in 1936. He studied in Prague and later taught for nine years at the Nautical School in Bakar. In 1892 was appointed director of the Meteorological Observatory in Zagreb. After a few years he taught at the University of Zagreb, and towards the end of the 19th century, he was a distinguished member of the Academy of Sciences in Zagreb. At the beginning of his scientific career he devoted much of his energy to meteorology, but had significantly more success in the field of seismology and founded the so-called “School of Zagreb,” which gained worldwide recognition in this field of science.
According to Mohorovicic’s theory, the seismic waves created by earthquakes at shallow depth, spread through the Earth’s interior. With his researches he discovered a discontinuity of speed that separates the crust from the mantle below. Later, scientists confirmed the correctness of Mohorovicic’s theory, and they recognized the existence of this discontinuity in all the continents and oceans. This theory was named, in honour of Mohorovicic, ” the Mohorovicic Discontinuity.”
Recently, mathematicians used computers to find the largest prime yet. It’s really big – it has over 17 million digits. If you printed it out in books, it would be roughly three times longer than all the Harry Potter books combined.
To make the number simpler to communicate, mathematicians have a different way of writing it: 257 885 161 – 1. This expression gives you a way of calculating the new prime number. First, take 57 885 161 ‘2’s and multiply them all together. Then subtract 1.
So you want to build a house, or a structure (say a theater), how do you go on about it? Other than acquiring the raw materials like cement, wood and steel you hire an architect to design the blueprint (ref. ayapelousdesigns.com) of the structure. This blueprint is the very thing that defines all about how you live which involves a surprising amount of creativity and math (ref. cfmathematics.com.au). To some architects this creativity comes naturally, however maths is a skill that can be acquired by all and is of great importance to architects (ref. jvqk.com). So how does designing a house involve math?

Tim was drawing an infographic about his chess club. The previous year, there were 8 members, but now there are 16. To represent the growth, he drew 2 square chessboards, one 8 cm wide, the other 16 cm wide. How many small boards would fit in the big board?
Jenny is really good at solving Rubik’s cubes. She has a smaller cube 10 cm tall, and a really big one that’s 20 cm tall. How many smaller cubes would fit in the really big one?
