Voltage, Current, Resistance, and Ohm's Law. Favorited Favorite 5 Electricity Basics When beginning to explore the world of electricity and electronics, it is vital to start by understanding the basics of voltage, current, and resistance. These are the three basic building blocks required to manipulate and utilize electricity. At first, these concepts can be difficult to understand because we cannot “see” them. Georg Ohm Covered in this Tutorial How electrical charge relates to voltage, current, and resistance.What voltage, current, and resistance are.What Ohm’s Law is and how to use it to understand electricity.A simple experiment to demonstrate these concepts.
Suggested Reading Electrical Charge Electricity is the movement of electrons. The three basic principles for this tutorial can be explained using electrons, or more specifically, the charge they create: Voltage is the difference in charge between two points.Current is the rate at which charge is flowing.Resistance is a material’s tendency to resist the flow of charge (current).

God Is a Question, Not an Answer. Common Knowledge and Aumann’s Agreement Theorem. The following is the prepared version of a talk that I gave at SPARC: a high-school summer program about applied rationality held in Berkeley, CA for the past two weeks. I had a wonderful time in Berkeley, meeting new friends and old, but I’m now leaving to visit the CQT in Singapore, and then to attend the AQIS conference in Seoul.
Common Knowledge and Aumann’s Agreement Theorem August 14, 2015 Thank you so much for inviting me here! I honestly don’t know whether it’s possible to teach applied rationality, the way this camp is trying to do. My research is mostly about quantum computing, and more broadly, computation and physics. I’ll start with the “Muddy Children Puzzle,” which is one of the greatest logic puzzles ever invented. OK, so the way it goes is, there are a hundred children playing in the mud. So the teacher tries again. Then the teacher tries something new. What’s going on here? Like with many puzzles, the way to get intuition is to change the numbers.
Infographic: 20 Cognitive Biases - Scientific Literacy Matters. First almost fully-formed human brain grown in lab, researchers claim | Science. An almost fully-formed human brain has been grown in a lab for the first time, claim scientists from Ohio State University. The team behind the feat hope the brain could transform our understanding of neurological disease.
Though not conscious the miniature brain, which resembles that of a five-week-old foetus, could potentially be useful for scientists who want to study the progression of developmental diseases. It could also be used to test drugs for conditions such as Alzheimer’s and Parkinson’s, since the regions they affect are in place during an early stage of brain development. The brain, which is about the size of a pencil eraser, is engineered from adult human skin cells and is the most complete human brain model yet developed, claimed Rene Anand of Ohio State University, Columbus, who presented the work today at the Military Health System Research Symposium in Fort Lauderdale, Florida. The ethical concerns were non-existent, said Anand. Stanford Encyclopedia of Philosophy. I Asked Atheists How They Find Meaning In A Purposeless Universe.
Philosophy Bro. Long-acting reversible contraception. Long-acting reversible contraceptives (LARC) are methods of birth control that provide effective contraception for an extended period without requiring user action. They include injections, intrauterine devices (IUDs) and subdermal contraceptive implants. They are the most effective reversible methods of contraception because they do not depend on patient compliance. So their 'typical use' failure rates, at less than 1% per year, are about the same as 'perfect use' failure rates. In addition to being long-lasting, convenient, and well liked by users, they are very cost effective. Typically, LARC users can save thousands of dollars over a five-year period compared to the use of condoms and birth control pills. Despite their safety and effectiveness LARCs are underutilized: only 15.5% of women worldwide use IUDs, and only 3.4% use subdermal implants. Methods Available LARC methods include IUDs and the subdermal implant: Efficacy Cost Promotion
Intrauterine Device (IUD) Birth Control and Side Effects. No One Murdered Because Of This Image. WASHINGTON—Following the publication of the image above, in which the most cherished figures from multiple religious faiths were depicted engaging in a lascivious sex act of considerable depravity, no one was murdered, beaten, or had their lives threatened, sources reported Thursday. The image of the Hebrew prophet Moses high-fiving Jesus Christ as both are having their erect penises vigorously masturbated by Ganesha, all while the Hindu deity anally penetrates Buddha with his fist, reportedly went online at 6:45 p.m. EDT, after which not a single bomb threat was made against the organization responsible, nor did the person who created the cartoon go home fearing for his life in any way.
Though some members of the Jewish, Christian, Hindu, and Buddhist faiths were reportedly offended by the image, sources confirmed that upon seeing it, they simply shook their heads, rolled their eyes, and continued on with their day. Sam Harris and Dave Rubin Talk Religion, Politics, Free Speech (Full Interview) Practical Ethics - Princeton University | Coursera. About the Course In this course you will be encouraged to think about some of the ethical issues that we all face in our daily lives, and as concerned, global citizens. The course will focus on the following topics: Brain death and persistent vegetative state When is a person dead?
In many countries death is now defined as “brain death,” but is this way of understanding death justified? How we define death is important, because it is connected to critical questions such as: When is organ donation permissible? When is it right to take someone off life support? And how should we treat individuals who are in a persistent vegetative state?
Abortion and the moral status of embryos and fetus Most people would argue that it is always wrong to intentionally take the life of an innocent human being. Making end of life decisions How do you distinguish wrongful killing from acts that are not regarded as wrong? Effective altruism We all spend money on items that are not necessities. Course Syllabus. Philosophy Courses | Coursera. Sam Harris vs Muslim apologists 1/3. The Euthanasia Debate – Singer v Fisher – Should Voluntary Euthanasia be Legalised? Euthanasia debate: Professor Peter Singer versus Archbishop Anthony Fisher OP. Does Science Prove God? No. I could just stop there, but I’ll elaborate. Earlier this year Prager University posted a Youtube video hosted by Eric Metaxas in which he argues that science is the best argument for the existence of god. (The text is the same as his 2014 WSJ article.)
It was nothing surprising – he simply trots out the old fine-tuning of the universe argument. (I wrote about this here, but it’s making the rounds again so I’ll take another swipe.) He starts, however, by quoting Carl Sagan from a 1966 Time article. Sagan said that there were only two criteria for life to exist, the right kind of star and a planet the proper distance from that star. he wrote: Given the roughly octillion—1 followed by 24 zeros—planets in the universe, there should have been about septillion—1 followed by 21 zeros—planets capable of supporting life. This of course was a rough order of magnitude estimate based upon what information we had at the time, prior to any exoplanets being discovered.
The Problem of Evil I. Introduction: The Logical Argument From Evil “Is [God] willing to prevent evil, but not able? Then is he impotent. Is he able, but not willing? Then is he malevolent. Is he both able and willing? Whence then is evil?” The list of arguments for and against the existence of gods/God is very long, so it is useful to bring some order into the debate by distinguishing two different types of arguments. The argument from evil is perhaps the strongest and most compelling argument against God’s existence. There are two basic approaches to the argument, one deductive/logical and the other inductive/probabilistic/evidential. The Empirical Premise: Widespread Horrendous Suffering Both, the logical and the evidential argument from evil invoke an empirical premise on the existence and scope of evil in the world. Human Suffering Induced by Humans: Sophisticated torture has existed at least since antiquity and has been used for a variety of purposes, among them sadistic pleasure.
The Logical Argument. Africa Is Way Bigger Than You Think - Scientific American Blog Network. Look at the usual flat map of the world and it appears that Greenland is nearly as big as Africa. But it’s not even close. Africa is 14 times larger. Flat maps significantly distort the sizes of countries and continents, the result of converting a spherical surface to a handy rectangle. The area of landmasses becomes increasingly exaggerated toward the poles. As a result, we tend to underestimate the size of countries close to the equator, and substantially overestimate the size of countries closer to the poles. On our actual planet, Africa is bigger than China, India, the contiguous U.S. and most of Europe—combined! Scientific American just published a correctly proportioned image to show how Africa swallows up these nations, with Japan thrown in. For the record, then, a list of geographic sizes is below.

God: Yes or No? Dinesh D'Souza vs. Peter Singer. Richard Carrier. Richard Cevantis Carrier (born December 1, 1969) is an atheist activist, author, public speaker, and blogger. He has a doctorate in ancient history from Columbia University where his thesis was on the history of science in ancient antiquity. He is a leading proponent of the Christ myth theory. Richard Carrier originally gained prominence as an advocate of atheism and metaphysical naturalism, authoring many articles on The Secular Web, and later defending his basic position in his book Sense and Goodness Without God.
Subsequently, he became interested in the question of the historicity of Jesus, authoring two books on the subject, Proving History and On the Historicity of Jesus. These books explain and utilize a historical methodology that employs Bayes' theorem for the purpose of historical inquiry; specifically within the context of Jesus studies. He has also contributed chapters to two books of atheist apologetics edited by John W. Work Public Debates Personal life
Alien Super-Civilizations Playing Great Game of Hide & Seek. Scientists have taken a hard look at 100,000 galaxies and have determined that none of them contain obvious heat signatures that might be produced by a super advanced alien civilization. That’s a helluva bummer isn’t it? This latest bit of alien bad news comes from Penn State University Researchers in a paper from the Astrophysical Journal Supplement Series called “Glimpsing Heat from Alien Technologies Survey” The idea and the assumptions behind this is that some super-advanced aliens would spread throughout their home galaxy.
Such an advanced culture would likely be able to harness vast energies to support this widespread colonization and other geeky things that such societies are wont to do. This is typical of what’s called Type III civilizations on the Kardashev scale. They could support their pursuits using the energy of an entire galaxy ( in case you were wondering, Humanity is a Type 0.724…lame right?) Satellite accumulated during its run starting in 2009.
And search they did. Adam, Eve, and Evolution. The controversy surrounding evolution touches on our most central beliefs about ourselves and the world. Evolutionary theories have been used to answer questions about the origins of the universe, life, and man. These may be referred to as cosmological evolution, biological evolution, and human evolution. One’s opinion concerning one of these areas does not dictate what one believes concerning others. People usually take three basic positions on the origins of the cosmos, life, and man: (1) special or instantaneous creation, (2) developmental creation or theistic evolution, (3) and atheistic evolution. Related to the question of how the universe, life, and man arose is the question of when they arose. The Catholic Position What is the Catholic position concerning belief or unbelief in evolution?
Concerning cosmological evolution, the Church has infallibly defined that the universe was specially created out of nothing. Concerning human evolution, the Church has a more definite teaching. Crucifixion. Crucifixion is a form of slow and painful execution in which the victim is tied or nailed to a large wooden cross and left to hang until dead. It is principally known from antiquity, but remains in occasional use in some countries. The crucifixion of Jesus is a central event in Christianity, and the crucifix (sometimes depicting Jesus nailed onto it) is the main religious symbol for many Christian churches.
Terminology Ancient Greek has two verbs for crucify: ana-stauro (ἀνασταυρόω), from stauros, "stake", and apo-tumpanizo (ἀποτυμπανίζω) "crucify on a plank,"  together with anaskolopizo (ἀνασκολοπίζω "impale"). In earlier pre-Roman Greek texts anastauro usually means "impale. " New Testament Greek uses four verbs, three of them based upon stauros (σταυρός), usually translated "cross". Details Crucifixion was often performed to terrorize and dissuade its witnesses from perpetrating particularly heinous crimes.

Concerning hell, C. S. Lewis once wrote, “There is no doctrine which I would more willingly remove from Christianity than this, if it lay in my power.” In many ways, I agree with him. No one, Christians included, should like the idea of hell. Those of us who believe in hell aren’t sadists who enjoy the idea of eternal suffering. Hell is a difficult reality, but it is something that the Bible teaches, and we can ’t fully understand God and his world unless we grapple with it. 1.
The doctrine of hell has fallen out of favor among many. Ironically, in doing away with hell, you do away with the very resources that show God’s justice. 2. The problem with this view is that when you start reading the Gospels, you find that Jesus speaks about hell more than anyone else. 3. The worst part was the separation from the Father that Jesus felt, a separation that was hell itself.
People often feel that hell is some great blemish on God’s love. 4. Elsewhere, Lewis wrote: 5. 6. 7. J.
