Pointless Sites - Useless Sites - Random websites - PointlessSites.com Your Sky by John Walker Welcome to Your Sky, the interactive planetarium of the Web. You can produce maps in the forms described below for any time and date, viewpoint, and observing location. Your Sky provides three ways to view the sky with links, where appropriate, among the various presentations. Sky Map The sky map shows the entire sky as viewed from a given location at a specified time and date. To make a sky map, enter the latitude and longitude of your observing site in the boxes below (be sure to check the correct “North/South” and “East/West” settings) and press the “Make Sky Map” button below the form. Horizon Views Horizon Views, showing the stars above the horizon as seen from a specified observing site at a given date and time. The Virtual Telescope Your Sky's Virtual Telescope is your Humble Soft Telescope of the Web. To launch the virtual telescope, enter the coordinates at which it should be aimed in the boxes below and push the “Aim Virtual Telescope” button. Your Sky help

Maths Online The following Flash movies simulate typical probability experiments. Carry out the experiments in the usual way with the whole class and then run the simulations to generate a large number of trials. The simulations couild be left running to produce thousands of trials.

Why do we believe in electrons, but not in fairies? by Benjamin Kuipers No one has directly observed either electrons or fairies. Both of them are theoretical constructs, useful to explain observations that might be difficult to explain otherwise. The "theory of fairies" can actually explain more things than the "theory of electrons". Is the issue a political one, where the "electron" fans got the upper hand in the nineteenth century, so by the twentieth century the "fairy" fans were a scorned and persecuted minority? No, to both. Fairies are much more free. It's always possible that there really are fairies. The scientific method is an amazing procedure for incrementally improving certain kinds of theories: those that make testable predictions. The theory of evolution is a scientific theory, because it implies a large number of specific testable claims. The theory of intelligent design could be true. The scientific method is an enormous intellectual asset to the human race. Atheism is a religion, too! Teaching better science

The above is an interactive infographic. We have also developed a complimentary poster that you can view here: Sizes of the Universe poster. Introduction: This interactive infographic from Number Sleuth accurately illustrates the scale of over 100 items within the observable universe ranging from galaxies to insects, nebulae and stars to molecules and atoms. While other sites have tried to magnify the universe, no one else has done so with real photographs and 3D renderings.

Become An Architect droite catho française Article mis à jour le 24 mai 2013. Une nébuleuse, plus qu’un collectif. Un label, plus qu’un mouvement. Apparu il y a un mois, à quelques jours de la manifestation du 24 mars contre le «mariage pour tous», le Printemps français intrigue. Et est désormais dans le collimateur du ministère de l'intérieur, qui a annoncé vendredi 24 mai étudier une possible interdiction du mouvement. La dégradation de l’Espace des Blancs-Manteaux (Paris) où se tenait le Printemps des associations de l’Inter-LGBT (lesbiennes, gays, bi et trans) dans la nuit de samedi 6 à dimanche 7 avril, c'étaient eux. Des membres de Printemps français lors de leur action à l'Espace des Blancs-Manteaux, à Paris, dans la nuit du 7 avril (photo extraite de leur vidéo). Le Printemps français ne s’en cache pas: il appelle à une «résistance à la Gandhi éventuellement illégale», selon le mot de sa porte-parole, Béatrice Bourges, lors d’un entretien au mensuel catholique d’extrême droite Monde et Vie.

How Secure Is My Password? Types of Mathematical Averages and Their Formulas In mathematics, the average of two or more numbers is called the mean. The most commonly used mean is called the arithmetic mean, in which you add up all the values and divide by the number of values. For example, the arithmetic mean of 2, 5, and 14 is (2+5+14)/3 = 7. However, there is more than one kind of mean, including the geomtric mean, harmonic mean, root mean square, and several others. The essential property of any mean is that it must fall between the highest value and the lowest value. Geometric Mean The geometric mean of two numbers x and y is sqrt(xy). (x1·x2·...xn)1/n Business analysts and scientists use the geometric mean to find the average growth rate of a process. sqrt[(1.25)(1.458)] = sqrt[1.8225] = 1.35 Thus, the average growth rate over the two years was 35%. Harmonic Mean In science in business applications, the harmonic mean is used to average ratios. n/(1/x1 + 1/x2 + ... + 1/xn) Root Mean Square (Quadratic Mean) sqrt[(x12 + x22 + ... + xn2)/n] Contraharmonic Mean

Simple Simulations l'anglais à l'université (France) Attablée dans une salle proche de l'hémicycle de l'Assemblée nationale, Geneviève Fioraso soupire de soulagement: "On va enfin pouvoir parler d'autre chose..." Jeudi 23 mai, en fin de matinée, le désormais fameux article 2 du projet de loi porté par la ministre de l'enseignement supérieur a été adopté par les députés . C'est cet article, plus que les 67 autres du texte, qui a focalisé les débats depuis deux mois. Il prévoit en effet de faciliter l'usage des langues étrangères, donc de l'anglais, dans l' enseignement supérieur français. Comme on pouvait s'y attendre compte-tenu de la vivacité de la polémique qui continue de s' enflammer par journaux interposés, le débat entre les députés a été, jeudi, particulièrement tendu. Lire le chat avec Yamina Benguigui, ministre déléguée chargée de la francophonie : La loi Fioraso ne met pas "la francophonie en danger" Car c'est de cela qu'il s'agit, estime Daniel Fasquelle . Sur les bancs de la gauche, le discours de M. "Ca ne va pas, non ?"

30 Challenges for 30 Days Did you know that it takes 30 days to form a new habit? The first few days are similar as to how you would imagine the birth of a new river. Full of enthusiasm it gushes forth, only to be met by strong obstacles. So, take a moment to reflect on the question ‘Who do I want to be in 5 years?’ Check out this short TED talk first to get inspired: Now pick one or more challenges and stick with them! However, be cautioned, picking too many challenges at the same time can easily result in a failure of all of them. #1 Write a I-Like-This-About-You note/text/email each day for someone (Easy) This is the perfect way to let someone else know you care. #2 Talk to one stranger each day (Hard) This is a great one to cure approaching anxiety. #3 Take one picture each day (Hard) This one gets harder nearing the end of the challenge because at one point you will run out of the easy shots. #4 Re-evaluate one long-held belief each day (Intermediate) #5 Take a 30 minute walk each day (Easy) We recommend:
