At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4. In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way. At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column. Although there were attempts to make relative age estimates, no direct dating method was available until the twentieth century. However, before this time some very popular indirect methods were available.

My class were studying a topic on the organisation of sport in the UK and were struggling to get to grips with all of the various organisational bodies and their roles. I therefore decided to have an interim revision session with a difference and used speed dating as the vehicle for this. I created seven questions based on what they had already learnt.
As each student came into the class, they were given one question each.

Wikimedia Deutschland speed dating at Wikimania Usually advance registration is required for speed dating events. Men and women are rotated to meet each other over a series of short “dates” usually lasting from three to eight minutes depending on the organization running the event. At the end of each interval, the organizer rings a bell, clinks a glass, or blows a whistle to signal the participants to move on to the next date.
At the end of the event participants submit to the organizers a list of who they would like to provide their contact information to. If there is a match, contact information is forwarded to both parties. Contact information cannot be traded during the initial meeting, in order to reduce pressure to accept or reject a suitor to his or her face.
Requirement for each event vary with the organizer. Specific age range based on gender is a common restriction for events. Many speed dating events are targeted at particular communities: Unlike many bars, a speed dating event will, by necessity, be quiet enough for people to talk comfortably. Participants can come alone without feeling out of place; alternatively it is something that women who like to go out in groups can do together.
Love At First Sight? Thank your medial prefrontal cortex, a brain region now discovered to play a major role in romantic decision-making. Different parts of this region, which sits near the front of the brain, make a snap judgment about physical attraction and about whether the person is Mr. Right — all within milliseconds of seeing a new face, a new study from Ireland finds. The research is the first to use real-world dating to examine how the brain makes fast romantic judgments.
For speed daters, first impressions are everything. But it’s more than just whether someone is hot or not. Researchers at Caltech have found that people make such speed-dating decisions based on a.
History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.
You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind.
Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.
Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations. They did not have the benefit of cheap, off the shelf, mass produced batteries.
For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item. In recent years batteries have changed out of all recognition. No longer are they simple electrochemical cells. Today the cells are components in battery systems, incorporating electronics and software, power management and control systems, monitoring and protection circuits, communications interfaces and thermal management.
Just like all previous events, it was a fantastic night. The event took place at the beautiful Rauschenberg Gallery Space in Chelsea. With scientists in the first row, artists in the second, the night began with two featured dates.
My friend, and fellow Diffusion Science Radio team member, Vanessa Gardos and I travelled down to Canberra for a Speed Dating extravaganza. There we heard a talk by our friend, and communicator extraordinaire, Lish Hogge on the science of speed dating, and got lost in the whole speed dating .
If you can use cardstock for these, they will be a bit easier to work with. Note that one complete set contains 14 cards 7 titles, 7 definitions. If your group has more than 14 people, you will need to print extra cards. Print the content examples for each of the seven CCC stations, as well as station signs numbered 1 — 7. If desired and if you have time you can add or swap in different examples of content to better suit the interests of your specific group of teachers.
Print copies of the CCC stations handout for participants. If desired, print the CCC stations key for your own reference. This activity is a basic introduction to the names of the seven CCCs and an opportunity to start learning what they mean and how content might be sorted among them. This will lay the foundation for deeper thinking about these ideas later on. CCCs speed dating 10 minutes Tell participants that the goal of the next activity is to give them a first introduction to how the Crosscutting Concepts CCCs are defined.
Have each participant blindly draw a card. That card will have either the title of a CCC e. Their task is to mingle around the room looking for their CCC match. If they have the title of a CCC, they are searching for the person who has the definition; if they have the definition, they are searching for the person who has the matching title.

One of the issues that I try to address in the classroom is to have each student talking with the other students about their academic work. If you have students in groups, some will dominate and some will play wall flower. With speed learning, students are challenged to have several one on one conversations with the other students. I communicate a defined outcome as well as a time limit to help focus the discussions. Steps for using the method in class: Use speed learning in cases where each student has something unique to share, it could be workshopping their project ideas or sharing a news article they were asked to being in.
Students arrange themselves so that each person is sitting across from one other person. Place a visible countdown timer so that students are able to manage their time well. Use a graphic organizer to focus the listener and facilitate active participation. Example from History of Anything project Have the students switch times depending on the desired outcome of the activity.

Speed Dating and Decision
Muharrem Oner Advertisement As a psychologist, I have always found the concept of speed dating fascinating. In fact, some years ago, I decided to try it myself. As you can imagine, I did not find the love of my life. Fortunately, the majority of people do not seem to share my particular troubles with speed dating. Yet new research does point out a different dating problem: In fact, it can even prevent you from a making a decision in the first place.

Researchers at the California Institute of Technology Caltech have found that people make such speed-dating decisions based on a combination of two different factors that are related to activity in But it’s more than just whether someone is hot or not. Whether or not we like to admit it, we all may make snap judgments about a new face. Perhaps nowhere is this truer than in speed dating, during which people decide on someone’s romantic potential in just a few seconds.
How they make those decisions, however, is not well understood. But now, researchers at the California Institute of Technology Caltech have found that people make such speed-dating decisions based on a combination of two different factors that are related to activity in two distinct parts of the brain. Unsurprisingly, the first factor in determining whether someone gets a lot of date requests is physical attractiveness. The second factor, which may be less obvious, involves people’s own individual preferences–how compatible a potential partner may be, for instance.
The study, which is published in the November 7 issue of the Journal of Neuroscience, is one of the first to look at what happens in the brain when people make rapid-judgment decisions that carry real social consequences, the researchers say. And almost nothing is known about how this type of rapid judgment is made by the brain. They were given four seconds to rate, on a scale from 1 to 4, how much they would want to date that person. After cycling through as many as 90 faces, the participants then rated the faces again–outside the fMRI machine–on attractiveness and likeability on a scale from 1 to 9.
