 The London International Youth Science Forum, LIYSF, was founded in 1959 with the idea of bringing young people from different nations together to learn about our diversity through a shared passion for science. We believe science is the intellectual and practical pursuit to understand the structure and behavior of the natural and physical world by experiment and observation. It touches each and every person's life throughout every moment in any day and it can help tackle modern challenges such as energy, food and water security, climate change, biodiversity and potential pandemics. In this digital age, the importance of face-to-face contact is critical, not only to fully understand the principles but also perspectives, cultures and attitudes. LIYSF is a two-week residential student event held annually, which attracts 500 of the world's leading young scientists age 16 to 21 years old from more than 70 participating countries from all around the world. Students are embraced into our international science community, each being selected to attend, having shown their passion and ability in science, technology, engineering or maths to represent their home country. LIYSF attracts the highest caliber of international speakers, including Nobel laureates, leading scientists, dignitaries and industry pioneers who lecture throughout. LIYSF is held at Imperial College London with day visits to prestigious UK research centres and universities, including Oxford and Cambridge University Departments and leading industrial sites such as Rolls-Royce, Airbus and Government facilities. Our mission is to give young people from all nations a deeper insight into science for the benefit of all mankind whilst enabling our students to develop lasting international friendships. This is LIYSF. Join us in moving science forward with the thinkers of the future.
