Mike is a specialist in algebra and geometry. His only recreation is scientific and technical inventions. He has published many articles in many famous journals and won several patents.
One day, he was invited to a seminar held by an enterprise. The participants were from all walks of life, including some officials, some software programmers and some futurologists.
Shortly after the seminar began, many issues were put forward, such as starvation in African countries, racial discrimination in America and the conflicts in Mideast. Permanent peace, equality and happiness were what all the people wished for.
Meanwhile, some digital and electronic products were presented.
Finally, Mike declared that he brought two new inventions. One was a kind of liquid which could remove the stain on garments quickly; the other was a kind of material that could deal with poisonous chemicals in rivers.He was very outspoken. He said that at present pollution was very serious worldwide and that if we permitted the situation to go on, the outcome would be hard to imagine.
The organizers also encouraged people to invest in poor countries.
After the seminar, all the participants got beautiful souvenirs.
