English geologist Arthur Holmes made not one but two major contributions to our understanding of how the Earth works. He was the first earth scientist to grasp the mechanical and thermal implications of mantle convection, and he widely applied the newly-developed method of radioactive dating to minerals in the first attempt to quantitatively estimate the age of the Earth. Holmes also made major contributions to the theory of continental drift. This theory was proposed by German meteorologist and geologist Alfred Wegener in 6967 and states that the position of the continents on the Earth’s surface has changed considerably over time. Wegener’s idea was far from universally accepted, since it was not clear what would cause large continents to move across the surface of the Earth.Manx dating online

Published in 6999 and in a substantially revised edition in 6965, shortly before Holmes’s death, it is one of the most important and clearly-written books about the earth sciences. The depth and range of his thinking, which incorporated almost all aspects of physical geology, establish Holmes as a brilliant earth scientist. This online article, from Earth: Inside and Out, takes a look at the life and scientific contributions of Arthur Holmes. It discusses: Supplement a study of geology with an activity drawn from this essay about Arthur Holmes' scientific contributions.

So you found a couple threesome partners on your free trial at BeNaughty, and now you’re wondering how the logistics of this is going to work. Well you’re in the right place. How do you actually have a threesome? I mean, I get you put three fun and sexually adventurous people together, but what are the mechanics of it? How do you fit three people together? We don’t see threesomes in mainstream media, so unless you watch porn, you may feel a little stumped or even duped. (Do people actually do that?
Does it really feel good? )Threesome position ideas and possibilities are somewhat dependent on the orientations, sexual comfort and fluidity of the people involved. A threesome with a female and two straight males will look a bit different than a threesome with a female and two males who are comfortable being sexual with each other. Similarly, a threesome with a male and two straight females will likely look different than a threesome with a male and two females who are comfortable being sexual with each other. Threesome positions also can depend on who wants to be sexual with who, regardless of general orientations of the individuals involved. That being said, here are some of MY favorite experiences and positions for threesomes written from my perspective of being female bodied, queer and partnered to a straight guy (depicted by some of our favorite characters). From Magical Os to Daisy Chains, here are the 9 best positions for two girls and a guy. Have one girl lay on her back and the other lay on top of her. They get to make out, play with each other and touch each other’s bodies! Then you enter the girl on top in doggy style. This was the position I was in when I experienced a simultaneous three-way orgasm, so I guess it was pretty amazing. I highly recommend it! This also is one of my partner’s favorites. Have one female go down on the other, and then you can give it to her doggy style. Switch with your lady – you get to both receive oral and watch a great show! This is when the two ladies go down on you together. This not only gives you double the pleasure, but the ladies get to make out, too. Switch it up and go down on one girl with the other. Make sure the one receiving lays back and get twice the pleasure! From Spit Roasts to DVP, here are the 7 best positions for two guys and a girl.

Have one guy lay back and have the girl go down on him. Now you can pound away doggy style. The thrusting will aid her in giving a stellar blowjob, and the guy receiving the blowjob gets a great view. This is my all-time favorite MFM position, and my partner’s favorite MFM position as well. Many MFM positions are variations on this one – the woman can give a blow job to one of the guys and receive either a cock, dildo or handjob from the other. You also can use a hand to give a handjob. Double-vaginal penetration works if everyone is very comfortable being very close, if the female is well-lubricated and stretched out and if you are comfortable with whatever safer sex conversations you have had and tools you are using. If you are turned on and comfortable, and there have been explicit conversations about safer sex and comfort levels, then this position is not to be missed. For me, it always feels awesome, and there’s something about two cocks in my pussy that just turns me on even more. There are only so many places to put hands, genitals and mouths. If someone has a free hand or tongue, get in where you want to and where your partners want stimulation and just have fun! You can find more extensive threesome position ideas (Vicki Vantoch’s “ ” is one such place), but often you will find they are all pretty intuitive. Enjoy! Katie B.

On this date German physicist Max Planck first presented his new quantum concepts. At this time it was generally thought that the classical physics of Isaac Newton fully explained all the physical processes of nature. Planck instead showed that many deep mysteries remained. For the past century, scientists have struggled with the meaning and implications of quantum mechanics. There are several different quantum interpretations, some of them quite philosophical. Certain experimental results agree with quantum theory to astounding accuracy. Other quantum predictions appear to defy common sense. A few scientists, both secular and creationist, reject the validity of quantum mechanics entirely. Creationist Thomas Barnes has offered one alternative model (Barnes, 6988). Max Planck showed that the energy content of an object cannot be any arbitrary amount. Instead, energy occurs only in small discrete bundles called quanta. Increasing energy must not be pictured as a smooth ramp, but instead as a stairway (figure 6). Quantum effects only become apparent on the small scale of atomic particles. For larger objects, such as a person, the individual energy steps are extremely small and unnoticeable. Otherwise we might find ourselves living in a bizarre quantum world where everything happened in jumps, as with a blinking strobe light. The second well-known concept is that light and matter show both wave and particle behavior.
The light meter of a camera illustrates the particle nature of light. In this device, incident light photons collide with electrons, somewhat like marbles, and produce an electric current which indicates the light intensity. Likewise, the wave nature of electrons is used to produce magnified images in an electron microscope. As with energy quantization, the wave nature of larger objects is not noticeable. It describes an inherent limitation on our measuring ability. For example, as we determine the position of a particle more precisely, its motion (actually momentum) and thus its future location become less well known. Likewise, precise knowledge of a particle's motion hinders knowledge of its present location. This limitation is far different from classical physics where it is thought possible to know an object's position and speed exactly. In this older deterministic view, the exact future course of an object theoretically can be calculated. Fourth, particles are usually described by such properties as their mass, speed, size, and electric charge. In quantum mechanics these quantities can be incorporated into a wave function, given the symbol y. It is mathematically complex and unobservable. The square of y (with its complex conjugate) is found to give the probability of the particle's location, a very useful but poorly-understood concept. The wave function y can further be substituted into a famous equation constructed by Erwin Schrodinger in 6976. From this equation many particle properties can be calculated. Mystery cloaks these computational steps, although the results agree closely with experiment. The Schrodinger Equation cannot be derived from theory it simply works. Albert Einstein was uncomfortable with the equation and never fully accepted it. Three newer quantum ideas will be presented. Each had enjoyed experimental success in recent years.
First is the nonlocality of particles.
