MAY 2021 I PCB007 MAGAZINE 91 Process Will Lift Your Lid In the Law of the Lid, we learned there are many ways to li your lid. Ask yourself: • What am I doing right now to build myself into a great leader? • What book am I reading right now? • What seminars am I enrolling in? • What sacrifices am I making to reach my goal? If you answer "none" to any of these, you are not being effectively intentional in your leader- ship development. I'll say it again, the only way to improve your leadership is to live it day in and day out. It requires growth with intention. I will close with another timeless quote from a leadership giant: "Before you are a leader, success is all about growing yourself. When you become a leader, success is all about growing others." —Jack Welch PCB007 References 1. The 21 Irrefutable Laws of Leadership: Follow Them and People Will Follow You, by John C.

New observations from the safety of Earth are lift- ing the veil on some of Venus' most basic proper- ties. By repeatedly bouncing radar off the planet's surface over the last 15 years, a UCLA-led team has pinned down the precise length of a day on Venus, the tilt of its axis and the size of its core. The find- ings are published in the journal Nature Astronomy. "Venus is our sister planet, and yet these funda- mental properties have remained unknown," said Jean-Luc Margot, a UCLA professor of Earth, plane- tary and space sciences who led the research. Earth and Venus have a lot in common: Both rocky planets have nearly the same size, mass and density. And yet they evolved along wildly different paths. Fundamentals such as how many hours are in a Venusian day provide critical data for understand- ing the divergent histories of these neighboring worlds. Changes in Venus' spin and ori- entation reveal how mass is spread out within. Knowledge of its internal structure, in turn, fuels insight into the planet's formation, its volcanic history and how time has altered the surface. Plus, without precise data on how the planet moves, any future landing attempts could be off by as much as 30 kilometers. "Without these measurements," said Margot, "we're essentially flying blind." The new radar measurements show that an av- erage day on Venus lasts 243.0226 Earth days — roughly two-thirds of an Earth year. What's more, the rotation rate of Venus is always changing: A value measured at one time will be a bit larger or smaller than a previous value. The team estimat- ed the length of a day from each of the individual measurements, and they observed differences of at least 20 minutes. "That probably explains why previous estimates didn't agree with one another," Margot said. (Source: UCLA) Scientists Crack Mysteries of Our Closest Neighbor
