My name is Mallory. I am Dana. I'm Michelle. I am Rosa. I am Ashley. My name is Jamie and I am. What are we doing here todayé I'm going to have a reallyintense look at my vagina.
I am going to show youwhat my vagina looks like. With my words. Oh and someone else is going to draw it. And get a little portrait of it. I'm going to pick out my vagina from like a lineup of different vaginas and pick which one's mine. It feels embarrassing and weird.
I kind of had to psychmyself out for this because it's like okay it's awkward but like there's noshame in having a vagina. I'm feeling curious. This is fun. I'm excited to see the results. I'm Caroline, I'm a professional portrait artist.
I've been drawing for eight years now and I've never drawn vagina portraits but I'm confident I can do it. Hi there. Hi. Nice to meet you. Have you ever had yourportrait drawn beforeé Not of my pussy.
You will be describingwhat you're seeing and I will be drawingexactly what you tell me. Okay and I use thismirror here and stuff. All right. Ooh, yip been a while. It's like weird. Yeah and it's just, it's there. Describe the lips.
Small. They're very even. Darker than any skin on my body. Maybe like two string cheese. Okay that's good. Is that good like that. That's perfect. I'm going to go ahead andget a rough sketch going.
Sunlight is way older than you think Sten Odenwald
You may know that it takes lighta zippy eight minutes to reach us from the surface of the Sun, so how long do you think it takes light to travel from the Sun's coreto its surfaceé A few seconds or a minute at mosté Well, oddly enough, the answeris many thousands of years. Here's why. Photons are produced by the nuclear reactions deep in the core of our Sun.
As the photons flow out of the core,they interact with matter and lose energy, becoming longer wavelength forms of light. They start out as gamma rays in the core, but end up as xrays, ultravioletor visible light as they near the surface. However, that journeyis neither simple nor direct. Upon being born, each photon travels ata speed of 300,000 kilometers per second until it collides with a protonand is diverted in another direction, acting like a bullet ricocheting offof every charged particle it strikes.
The question of how far this photon getsfrom the center of the Sun after each collision is known as the random walk problem. The answer is given by this formula: distance equals step size times the squareroot of the number of steps. So if you were taking a random walk from your front door with a one meter stride each second, it would take you a million stepsand eleven days
just to travel one kilometer. So then how long does it take for a photongenerated in the center of the sun to reach youé We know the mass of the Sun and can use that to calculate the numberof protons within it. Let's assume for a second that all the Sun's protons are evenly spread out, making the average distance between themabout 1.0 x 10^10 meters. To random walk the 690,000 kilometersfrom the core to the solar surface
would then require 3.9 x 10^37 steps, giving a total travel time of 400 billion years. Hmm, that can't be right. The Sun is only 4.6 billion years old,so what went wrongé Two things: The Sun isn't actually of uniform density and photons will miss quite a few protonsbetween every collision. In actuality, a photon's energy,
which changes over the course of its journey, determines how likely it is to interact with a proton. On the density question, our models show that the Sunhas a hot core, where the fusion reactions occur. Surrounding that is the radiative zone, followed by the convective zone,which extends all the way to the surface. The material in the core is much denser than lead,
2015 Water Industry Report Seeking Comprehensive Water Resilience Strategy
For years the water industry has struggledwith the ability to quickly rebound after major disruptions to our systems. How do wemanage water infrastructure in the face of extreme weather events, longterm changesin climates, or the challenges of aging infrastructureé What steps must be taken to manage these assetsand capital so that we remain financially healthy and provide reliable serviceé How does thewater industry become more resilienté Our 2015 Strategic Directions: US Water IndustryReport examines resilience from a number of angles financial, strategic, and operational.Achieving resilience through fiscal soundness, diversity of resources and the ability torespond and rebound from system shocks are
at the top of the industry's priority list.Multiple forces are driving utilities to measure their resilience. Our report offers a tellingsnapshot of how resilience is considered by utilities. Nearly a third of respondents saythey're actively measuring resilience through outage metrics, recovery time and customersatisfaction. But nearly fourinten respondents have not yet developed a strategy to becomemore resilient. Many stakeholders may not fully appreciate the planning andwork that is required to effectively manage assets and maintain reliable service. Theyare quick, however, to challenge utilities when something goes wrong, or when they don'tperceive value in exchange for rising rates.
That's what makes resilience such a coreelement of strategic planning and creates the need to engage all stakeholders in theprocess. Organizations that takesteps now to assess their systems and plan for future challenges will be positioned toquickly bounce back from the challenges we all will inevitably face.
