For the fourth time, the IdeenExpo will turn the fairgrounds in Hannover into the “largest classroom in the world”. Working under the motto of “Your ideas can make a change”, 550 hand-on experiments around natural sciences and technology will tickle the senses for nine days.
In this year, there will be six colored “idea paths” that are spun like a web over the fairgrounds connecting and complementing the different idea paths. The LZH is on the red “material – design – products” path, and will be showing the versatility of the tool laser. At stand MDP-06, young people will be able try out 4 interesting hands-on experiments using laser technology.
Laser on Air
Sending signals using light is state of the art, and modern communications use optical technology. On the way from sender to receiver, telephone calls and e-mails are transformed into signals moving at the speed of light. Test whether music can be sent by light at the LZH stand. Is it possible to connect music from an MP3 player to loudspeakers without using wiring? Different light sources can be used, which can be guided directly to a receiver, or via mirror reflection. But how does the music actually reach the loudspeaker?
„Guess how far“
Try measuring something longer than 2 meters, if your measuring tape or stick is shorter! What are the alternatives to using a measuring stick end to end to end? Guessing isn’t very exact! Exact measurements over long distances are possible using a laser rangefinder by just reading the answer from the display. At the LZH stand, you can explore the technology behind this 40 meter long “measuring stick”, and find out just how exact your guessing is!
Components out of thin air
3-D printers are quite the rage, even if they are usually viewed as technical toys. However, this technology actually has a very promising future. The 3-D printer at the LZH stand was built by school pupils, and there are hardly limits to what it can do, since it uses open-source hardware and software, and last not least due to the know-how of the LZH scientists who work with industrial additive manufacturing. Watch the 3-D printer in action and let yourself be surprised.
Laser goes LEGO® - Brand new LEGO® Robot transforms into a laser station
What can’t be done with the new Mindstorms EV3-Roboter from LEGO®? Our scientists made a model of a laser processing station with LEGO®, and had fun in doing so. If they had had more parts and more time, who knows what they would have done? The robot has access to many tools, and the potential for many new developments is just around the corner. Even though professionals use the software LabVIEW™, it is easy to program.
If you want to have fun learning about new technologies and about what the future has in hold, don’t forget to visit the LZH scientists at stand MDP-06 at the Ideen Expo!
The LZH thinks it is important to give young people insights into the fascinating world of laser technology. The Laser Zentrum Hannover e.V. in the science park in Hannover/Marienwerder offers young people the chance to gather experience with, and information on laser technology. The LZH offers practical courses for pupils in which they accompany a scientist working with laser technology, a “volunteer scientific year”, or apprenticeships or practical studies in different thematic areas of the institute. More information can be found at the LZH stand at the IdeenExpo in Hannover.

The Light: Global study gets underway with online user survey
Light has a fundamental impact on our sense of well-being and performance.

The objective is to identify the best lighting conditions for a variety of spaces and lighting ...
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
But here’s the catch: One couldn’t actually ...
A star is formed when a large cloud of gas and dust condenses and eventually becomes so dense that it collapses into a ball of gas, where the pressure heats the matter, creating a glowing gas ball – a star is born.
New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was initially about 100 times brighter than it is now. The results are published in the scientific journal, Astrophysical Journal Letters.
The young ...
