WEBVTT 00:00:02.410 --> 00:00:06.049 Hi, if you have ever taken calculus, you may 00:00:06.049 --> 00:00:10.550 recognize weird expressions like dy over dx. 00:00:11.150 --> 00:00:14.429 Or how about that elongated s that we use for 00:00:14.429 --> 00:00:17.769 integration? These symbols were introduced more 00:00:17.769 --> 00:00:21.410 than 300 years ago by Gottfried William Leibniz. 00:00:22.109 --> 00:00:25.109 Now, Isaac Newton was also developing calculus 00:00:25.109 --> 00:00:28.030 around the same time, but he used different notation. 00:00:29.190 --> 00:00:32.710 However, much of Leibniz's notation eventually 00:00:32.710 --> 00:00:38.369 became the standard. Why? Well, it's not because 00:00:38.369 --> 00:00:41.689 his calculus was more true, but it was because 00:00:41.689 --> 00:00:45.570 his notation communicated ideas more clearly. 00:00:46.090 --> 00:00:51.710 For example, dy over dx help us see how a change 00:00:51.710 --> 00:00:56.070 in y relates to a change in x. The integral symbol, 00:00:56.369 --> 00:00:59.969 the elongated s, is an elongated s to represent 00:00:59.969 --> 00:01:05.890 a sum. The notation carries meaning. Mathematics 00:01:05.890 --> 00:01:08.650 is not only about discovering truth, but it's 00:01:08.650 --> 00:01:11.370 about finding good ways to communicate truth. 00:01:12.329 --> 00:01:15.450 And I think that's true of a lot of things, like 00:01:15.450 --> 00:01:19.390 our relationships. Sometimes I know exactly what 00:01:19.390 --> 00:01:23.489 I mean, so I assume the other person knows that 00:01:23.489 --> 00:01:30.370 too. But words like soon, support, respect, and 00:01:30.370 --> 00:01:33.500 trust may mean different things to different 00:01:33.500 --> 00:01:37.719 people. Sure, most people would agree trust is 00:01:37.719 --> 00:01:45.040 important. But what exactly is trust? Well, researcher 00:01:45.040 --> 00:01:49.019 Brene Brown used the acronym BRAVING to define 00:01:49.019 --> 00:01:52.760 it. And this was life -changing for me. So here 00:01:52.760 --> 00:01:56.280 is the BRAVING. Boundaries. I respect what is 00:01:56.280 --> 00:02:01.060 okay with you. Reliability. I do what I say I 00:02:01.060 --> 00:02:05.700 will do. Accountability. I own my mistakes and 00:02:05.700 --> 00:02:09.860 I try to make them right. Vault. I protect what 00:02:09.860 --> 00:02:14.699 is not mine to share. Integrity. I choose what 00:02:14.699 --> 00:02:20.099 is right over what is easy. Non -judgment. We 00:02:20.099 --> 00:02:24.259 can ask each other for help without shame. In 00:02:24.259 --> 00:02:28.039 generosity. I interpret your words and intentions. 00:02:28.979 --> 00:02:34.020 As generously as I reasonably can, I really like 00:02:34.020 --> 00:02:37.379 the last one. When someone says something that 00:02:37.379 --> 00:02:42.060 hurts me, or maybe just frustrates me, do I immediately 00:02:42.060 --> 00:02:46.919 assume the worst? Or do I leave room for the 00:02:46.919 --> 00:02:50.979 possibility that I misunderstood, that they express 00:02:50.979 --> 00:02:54.099 themselves poorly, or that they are carrying 00:02:54.099 --> 00:02:57.919 something I know nothing about? Generosity does 00:02:57.919 --> 00:03:01.699 not mean ignoring harmful behavior. Boundaries 00:03:01.699 --> 00:03:04.620 and accountability are part of the equation of 00:03:04.620 --> 00:03:08.039 trust as well. It simply means I do not rush 00:03:08.039 --> 00:03:12.860 to assign the worst possible motive. Two people 00:03:12.860 --> 00:03:16.319 may both say I want a relationship built on trust, 00:03:16.419 --> 00:03:20.919 but imagining different things. A definition 00:03:20.919 --> 00:03:25.000 gives them something concrete to discuss. It 00:03:25.000 --> 00:03:28.439 transformed trust from a feeling we hope to preserve 00:03:28.439 --> 00:03:33.699 into practices that we can choose. I have a life 00:03:33.699 --> 00:03:37.300 coach of mine who's a friend named Jill. She 00:03:37.300 --> 00:03:41.979 told me that clarity is kindness. And maybe that's 00:03:41.979 --> 00:03:45.020 one lesson that we can learn from Leibniz. Good 00:03:45.020 --> 00:03:47.780 language does not merely express what I know. 00:03:48.099 --> 00:03:53.789 It helps someone else to see what I mean. So 00:03:53.789 --> 00:03:56.729 here's something to ponder today. What does trust 00:03:56.729 --> 00:04:00.710 mean to you? And have you made that meaning clear 00:04:00.710 --> 00:04:04.849 to the people you hope to trust and who you hope 00:04:04.849 --> 00:04:08.770 will trust you? Sometimes better understanding 00:04:08.770 --> 00:04:10.930 just begins with a better definition.
