1 00:00:01,800 --> 00:00:04,980 I remember when I worked for the American Dental Association. 2 00:00:04,980 --> 00:00:10,110 So I remember telling people Oh to design a material to to survive the oral 3 00:00:10,110 --> 00:00:12,630 environment is so challenging, it's really tough. 4 00:00:12,630 --> 00:00:18,150 There's abrasion, prescription medication, you have ice cream, piping hot coffee 100 5 00:00:18,150 --> 00:00:24,630 degrees or more. Every 45 minutes we've got solar radiation, x-rays, thermal 6 00:00:24,630 --> 00:00:29,680 cycling, atomic oxygen, the UV radiation and the harsh vacuum of space. 7 00:00:30,700 --> 00:00:35,800 And then I went to work for NASA. And people ask me what I do and I say oh it's so challenging. 8 00:00:35,800 --> 00:00:40,820 (music) 9 00:00:40,820 --> 00:00:49,940 (music) (ambient sound) 10 00:00:49,940 --> 00:00:54,220 Much of my job is failure analysis when this material fails in 11 00:00:54,220 --> 00:00:56,440 orbit like the outside of the blanket. 12 00:00:56,440 --> 00:00:59,100 (music) 13 00:00:59,100 --> 00:01:04,700 It's basically being a detective. Oh my gosh how the heck are we gonna know what 14 00:01:04,710 --> 00:01:09,299 happened to this incredibly complicated instrument on this incredibly 15 00:01:09,299 --> 00:01:15,450 complicated satellite, that's 250 miles in space going 18,000 miles an hour that 16 00:01:15,450 --> 00:01:19,020 we're not gonna get to for two or three years. But you slowly pick away at the 17 00:01:19,020 --> 00:01:24,180 problem, you got a lot of smart people who are going systematically checking 18 00:01:24,180 --> 00:01:26,430 off the list what is credible and non credible. 19 00:01:26,430 --> 00:01:28,680 I mean it's it's a puzzle, it's a riddle. 20 00:01:28,680 --> 00:01:30,680 (music) 21 00:01:30,680 --> 00:01:32,440 I started focusing on science and math 22 00:01:32,440 --> 00:01:37,930 in middle school and in in high school. I went to college and got a degree in 23 00:01:37,930 --> 00:01:44,140 chemistry. The thrill of being able to you know, know have insight into what's 24 00:01:44,140 --> 00:01:48,910 really going on at the at the molecular level. It's just really exciting for me. 25 00:01:48,910 --> 00:01:53,070 Not just accepting that it happens, but digging into it, 26 00:01:53,070 --> 00:01:59,590 figuring out why. My degree is in chemistry and I do a lot with chemistry, 27 00:01:59,590 --> 00:02:06,130 with material science engineering, with physics, but more important than all of 28 00:02:06,130 --> 00:02:08,020 those is English. 29 00:02:08,020 --> 00:02:14,300 (music) (ambient sound) 30 00:02:14,300 --> 00:02:18,900 So if you cannot communicate your needs, your opinions, 31 00:02:18,900 --> 00:02:23,580 your engineering judgment, little else matters. 32 00:02:23,580 --> 00:02:25,580 (music) (ambient sound) 33 00:02:25,580 --> 00:02:33,720 Engineering, chemistry, they all share the common goal of making sense being able to draw general 34 00:02:33,720 --> 00:02:42,680 conclusions from a host of individual examples. So you can then use that information in the future. 35 00:02:42,680 --> 00:02:55,280 (music)
