Welcome to the 21st episode of the SciTalksGR series, a monthly discussion about science (and more). Our guest is Chemist Dimitris Theodosopoulos, creator of the Smart Chemitry channel. Some of the topics covered in this episode are the Perseverance mission and landing on Mars, chemistry in our everyday lives, and self-driving vehicles. The contents and sources for all the topics discussed are below. == Electric cars, battery technology and autonomous driving: [18:50] ►The landing, tools and mission of NASA's Perseverance Rover on Mars: [35:20] ► Atmospheric conditions on Mars, misconceptions about signs of life on the planet and what we can learn from its exploration: [45:40] ► Possible use of aerogel material to create greenhouses that will allow safe food cultivation on Mars: [52:55] ► Temporary improvement in atmospheric conditions, evolution of distance learning and other small positive news in the midst of the pandemic: [57:30] ► How can chemistry teaching be made more interactive and interesting? Brief demonstration of chemistry experiments: [01:07:37] ► The properties and applications of graphene in medicine, ecology and technology: [01:18:32] ► How investing money in scientific research can have significant benefits in improving our everyday lives: [01:32:26] ► What is the anthropic principle: [01:36:15] ► Development of a device that simulates any taste and its possible applications: [01:40:56] ► Advice to children preparing for the national exams: [01:46:26] ►Closing: [01:50:40] == 2.
