Chapter 3 Classical physics could not explain the spectra of black bodies. It predicted that the intensity (power emitted at a given wavelength) of emitted light should increase rapidly with decreasing wavelength without limit (the "ultraviolet catastrophe"). In the figure below, the curve labeled "Rayleigh-Jeans law" shows the classically expected behavior. However, the measured spectra actually showed an intensity maximum at a particular wavelength, while the intensity decreased at wavelengths both above and below the maximum. E = hf (Planck's formula) where h (Planck's constant) is an exceedingly small number whose value we do not need here, and f is the frequency of vibration of the oscillator (the number of times it vibrates per second). Also in the late 1800s, experimental physicists were measuring the emission of electrons from metallic objects when they shined light on the object. 3.2. Line spectra are another example of phenomena that could not be explained by classical physics. l=h/p
Guide to flirting Why do we flirt? Flirting is much more than just a bit of fun: it is a universal and essential aspect of human interaction. Anthropological research shows that flirting is to be found, in some form, in all cultures and societies around the world. Flirting is a basic instinct, part of human nature. This is not surprising: if we did not initiate contact and express interest in members of the opposite sex, we would not progress to reproduction, and the human species would become extinct. According to some evolutionary psychologists, flirting may even be the foundation of civilisation as we know it. If flirting is instinctive, why do we need this Guide? Like every other human activity, flirting is governed by a complex set of unwritten laws of etiquette. We only become aware of the rules when someone commits a breach of this etiquette – by flirting with the wrong person, perhaps, or at an inappropriate time or place.

Donna Williams: Left and Right Brain Dominance I enjoyed this website (below) so wanted to pass it on. Its all about right versus left brain dominance... basically we have two sides of the brain and they do different jobs. Almost all of us use both sides, but some of us will be more dominant in one than the other and some of us will have more integration between the two than other people will. Till I was nine I struggled to understand language with meaning AT ALL and my receptive processing for meaning was about 10%, the effect was I was tested for deafness and also found unable to understand written words for meaning. Even once I got 50% meaning from words I still couldn't follow instructions because 50% of it went unprocessed for meaning and the rest was tumbled, like the sequencing didn't hold. I'm the kind of person who learns through doing, through physically having contact with a sequence or touching the objects used to symbolise parts of a story or explanation. I did the test in the site below.
Why you should learn to lucid dream | Yes, I Can! by Robin Nixon If you’ve never experienced it then you may find it hard to understand what lucid dreaming is all about. In fact you may be thoroughly sceptical and dismiss the whole thing as silly nonsense. But I can tell you from personal experience that lucid dreams are very real and something that many millions of people regularly enjoy. Note: Due to the huge amount of interest that this post has generated I am now seriously considering writing a book on the subject, and I would welcome input from anyone with an interest. These types of dreams are hyper-real in that when you experience one it is bursting with vibrant colour, there’s often marvellous music playing in the background (if you listen for it), the air is the freshest and sweetest you’ve ever smelled, and you are the healthiest you have ever been (or could ever be). Lucid dreaming is when you experience full consciousness while dreaming. When you ‘wake up’ inside a dream you can consciously appreciate just how wonderful dreams really are.

About our meditation classes | free meditation classes Meditation is a practice which is essentially simple, yet profound in its effect. It helps us quieten the mind and enter into the heart. It is a way of tapping into a source of tremendous strength we have within us. Sri Chinmoy wrote, ‘When we meditate, what we actually do is enter into the deeper part of our being. At that time we are able to bring to the fore the wealth that we have deep within us.’ At Sri Chinmoy’s request, these meditation classes are free, offered as a service, as Sri Chinmoy himself never charged for his teaching, his inspiration. In the introductory classes you can learn a variety of techniques tohelp you meditate: Control of the breath (pranayama). We will also discuss ways of integrating your meditation practice into your everyday life, setting out on your own inner journey. ‘Meditation helps us to live from moment to moment.’ – Sri Chinmoy
What Does Your Body Language Say About You? How To Read Signs and Recognize&Gestures - Jinxi Boo - Jinxi Boo Art by LaetitziaAs we all know, communication is essential in society. Advancements in technology have transformed the way that we correspond with others in the modern world. Because of the constant buzz in our technological world, it's easy to forget how important communicating face-to-face is. When conversing old-school style, it's not only speech we verbalize that matters, but what our nonverbal gestures articulate as well. Body language is truly a language of its own. 10% from what the person actually says40% from the tone and speed of voice50% is from their body language. Lowering one's head can signal a lack of confidence. Pushing back one's shoulders can demonstrate power and courageOpen arms means one is comfortable with being approached and willing to talk/communicate

Witajcie! Witajcie! Zainspirowany komentarzem użytkownika syrena_elektro postanowiłem napisać kilka rad i wskazówek dla ludzi którzy chcą zacząć uczęszczać na siłownie. Sam specem w temacie nie jestem jednak postaram się podzielić z Wami tym czego nauczyłem się podczas 1.5 roku swoich treningów na profesjonalnej siłowni a później swojej własnej domowej. Wiedzę czerpałem najpierw od instruktorów a później z internetu, w większości przypadków z forum sfd.pl + własne doświadczenia, próby i eksperymenty. Jeśli napiszę jakąś bzdurę, fachowcy niech mnie poprawią. Na początek: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. -pierwszy dzień treningowy: Klatka + Biceps -drugi dzień treningowy: Plecy + triceps -trzeci dzień treningowy: Nogi + barki Pamiętaj aby co jakiś czas zmieniać te zestawy i ćwiczenia bo mięśnie się przyzwyczajają a wtedy wolniej rosną. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27.
Part of Nature cartoon by Stuart McMillen This cartoon is heavily influenced by the books Natural Capitalism - Paul Hawken, Amory Lovins and Hunter Lovins (1999) and Mid-Course Correction - Ray Anderson (1998). It is also in the same vein as the flash animation "The Story of Stuff" by Annie Leonard, which I watched when I was about 90% of the way through the drawing process. Back to post / website.
