Conspiracy theorists will probably have little to say now that the Mars Reconnaissance Orbiter has taken the clearest photo yet of the alleged “Face on Mars” in Cydonia. For the before and after photos, see PhysOrg. The new photo is clearly an eroded, rocky mesa – that’s all, folks.Use this as a teachable moment. See our 09/21/2006 entry on design detection and the use of evidence to support a theory. Most serious human observers of Mars never bought into the late-night-talk-show fantasies (05/24/2001), but there is a serious question in such cases that needs reflection: how do we humans differentiate between design and chance or natural law? Look at our long list of paired objects, some designed, some not. A pictorial presentation of these pairs for kids can be a great way to help them think logically about design. Some of them are trickier than at first glance; they raise additional questions about deeper levels of design, and what we mean by design and natural law, that can trip up adults, too. And some of the most ardent scientific opponents of the Face-on-Mars idea have a puzzle of their own: how did they use intelligent design theory to show the believers were wrong? Moreover, how do they justify the inference of alleged microbes on Mars from methane, color, or other indirect biomarkers? Dumb as the Face-on-Mars theory was, it can be turned into a lively discussion on important questions, and can refine everyone’s baloney detecting skills.(Visited 8 times, 1 visits today)FacebookTwitterPinterestSave分享0
16 September 2015The National Heritage Monument, made up of life-sized bronze statues of precolonial, colonial and anti-apartheid struggle heroes and heroines, at the Groenkloof Nature Reserve in Pretoria, was unveiled on 15 September.There are already more than 50 statues at the monument, but it will eventually house 400. Known as the Long Walk to Freedom, it reflects the country’s journey from the precolonial era to the early wars of dispossession, as well as encompassing the entire liberation struggle.A walk through the newly erected #HeritageMonumentpic.twitter.com/D6gyKao7cu— Lirandzu Themba (@LirandzuThemba)September 15, 2015Some of the statues already erected include the likes of Walter and Albertina Sisulu, Yusuf Dadoo, Charlotte Maxeke, Solomon Tshekiso Plaatje, Alexander Simons, and King Mzilikazi Khumalo.Cast in bronze, struggle icons Walter and Albertina Sisulu will forever hold hands at the National Heritage Monument.

It will tell the story that our freedom was not free.”A must see for tourists“We want this to be a tourism attraction. We want it, in its completeness, to offer a number of things like hospitality and arts and crafts,” Tshwane Mayor Kgosientso Ramokgopa said on SABC news.“It’s going to be a major tourist attraction but also an area where a nation would be able to reflect so that we are able to plan for our future,” said Arts and Culture Minister Nathi Mthethwa.Full historyMthethwa said the South African story had been one-dimensional. This was being corrected through the heritage monument, which was giving a full picture of the country’s history.“We are writing our own story and it is important that we do that because we have to tell the world how we reached 27 April 1994,” Mthethwa said. It was also important to know our history, whether it was good or bad.Many more to see#NHM at #[email protected]#Myheritage.

2 July 2014President Jacob Zuma was on Tuesday presented with 4 850 books of condolences for Nelson Mandela, sent by South African embassies around the world and government offices around the country – and the books, along with thousands of message cards, are still coming in.South African missions abroad, and government offices at home, opened condolence books for people to pay their respects to Mandela following his passing away in Johannesburg on 5 December.Zuma paged through some of the books on Tuesday as Mandela Month got under way in South Africa, where July is dedicated to national humanitarian service in honour of the great man.Mandela’s birthday, 18 July, has been designated by the United Nations as International Mandela Day, when people around the world are urged to dedicate at least 67 minutes of their time to doing work in service of humanity.“I wish to thank all the people of South Africa and also the people of the world for taking their time to sign condolence books and to pay tribute to our beloved world icon, Tata Madiba, and to comfort his family,” Zuma said in a statement.“Let us make this a month of reflection and of building a caring society … in memory of Madiba and all heroes and heroines of our struggle for liberation. Let us work together to build the South Africa that Madiba dreamed about and worked for.”‘You made us who we are today’The Presidency shared the following selection of messages from the condolence books:“Our father may be gone but the ‘Madiba magic’ still lives on in our hearts.” (Mavis Sebothoma, Gauteng province)“A true leader who fought for liberty. The nation will forever love and cherish you.” (Sne, KwaZulu-Natal)“To our beloved Father of the Nation you made us for who we are today. You made us proud and taught us to stand for ourselves. Without you the world is nothing. Thank you Tata for being our hero. May your soul rest in peace.” (Molebogeng Setlhare, North West)“A man of great tenacity and unimaginable wisdom.

As you can see, there are a ton of options for working with rolling titles and credits in Premiere Pro. Experiment and have fun with it! Use a transition – perhaps the default Cross Dissolve – at the start and the end of your title. This will fade it in and fade it out for that professional look you’re after. When your titles come to an end, Premiere Pro will want to start from the beginning of your whole timeline which is a bit of a pain. So, trim your work area bar to just the length of your titles plus a little of the previous clip. This will allow you to see the transition for clip to title without having to go back to the start of the timeline. Rolling titles are a must for any professional film production. There are a few things that you need to know in Adobe Premiere Pro to make the process of creating rolling titles an easier one.Titles can be created in a number of ways in Adobe Premiere Pro.You could, for example, use the keyboard shortcut: CONTROL + T (PC) or COMMAND + T (Mac). You could click the ‘new items’ button at the bottom of the project panel or access the title tool through the menu bar – File > New > Title.*These options are great for a static title, but what about a rolling one? From the menu bar choose Title > New Title > Default Roll.The advantage of doing it this way is that it will create a new title with the right options in place for setting up the roll.*Note: if you want to convert a static title into a rolling one click the Roll/Crawl option box……and select the ‘Roll’ option in the dialogue box that appears:Don’t worry about the other options just yet, we’ll come to them later.Creating a Text Area in PremiereNext, we need to create a text area. Rather than just selecting the text tool and starting to type – which will create ‘point text’ (text that continues off the screen and will not wrap around) – you need to create ‘area text‘ and this can be done in one of two ways.First, you could select the Area Type Tool……and then drag out an area from the top left of the inner box (called the title safe area) to the bottom right of the same inner box. Simply click inside this area to add text.Another option is to drag the Standard Text Tool inside the box in the same way:Then, when you have finished the text cursor should be flashing. If it isn’t, just click in the new area you have created with the standard ‘T’ text tool and you are ready to start creating your titles.Font, size, etc are all up to you, but for this example I used a very large font and started to type out some names until they went off screen.Once text has gone off screen you get the little ‘+’ sign, which is simply telling you that there is more text than shown. S o, how do you show that text to create the rolling title?Rolling Titles in PremiereFirst, MAKE SURE YOU HAVE THE TEXT TOOL SELECTED!I have seen people really struggle to create a rolling title in the past because they have the wrong tool selected when they do this next step. It is very important that you have the text tool selected or else you will not be able to create a rolling title.Secondly, hold the Control Key (on PC) or Command Key (on Mac), and drag the handle at the middle of the bottom of the screen until you can see the next text (as shown below)…HandlesAbove I have shown the handles that will appear all around the screen when you hit the CTL/CMD key. To create the rolling title choose the middle bottom ‘handle’.Drag ArrowWhen you hover over that handle you will get this up/down arrow. Click and hold your mouse button and drag down until you see all the text you have created so far. When you let go you will see something like the following.After Dragging the HandleNow it moves into a process of repeating the same thing over and over. Type the next names in until they go off screen and then hold the CTL/CMD key and drag down and let go when you can see all the text.Lastly, when you’ve got all your list of credits into the title, hit return a few time then CTL/CMD drag down to a point where the names are off the top of the screen and you can type something like:Copyright 2012All rights reservedNote, if you want the © symbol on a PC the shortcut is Alt + 0169 on the main keyboard. For a MAC the shortcut is Alt + G.OK, now you’ve set up the title, use that scroll bar on the right-hand side to preview how your title will look. If something looks wrong, change it! If a name is still on screen at the top when you get to the end of the scroll – add in another line. If the copyright notice is too low, CTL/CMD + drag down just enough to get it in the right place – but be careful not to drag too much!Roll/Crawl Options in PremiereWhen you are happy with the way it scrolls, you are ready to move to the next stage – those roll/crawl options I previously mentioned.Roll/Crawl Options… and let’s have a look at each of these options in detail.PrerollHow long after the title appears do you want the title to wait before it starts rolling up the screen?For me, I usually choose the ‘Start Off Screen’ option and have the title background appear first and then have the text start to roll up from below the bottom.However, if you want the text to start on the screen and then start to roll up choose a Preroll amount IN FRAMES – not seconds! So, if you are working with NTSC (US and Japan) that would be 30 frames per second. For PAL (UK, Europe and much of the rest of the world) that would be 25 frames per second. Thus, if you wanted the text to stay put for 2 seconds before it started to roll you would type 60 (NTSC) or 50 (PAL) into the Preroll box.Ease-InHow slowly do you want to text to start moving?For example, if you have 0 in this box the text will start to move at once with no ‘easing’ which can look very amateur!What you want (if you start with the text on the screen) is the text to smoothly start to scroll up the screen starting very slowly and getting faster. So, if you wanted it to accelerate over say 1 second you would type 30 (NTSC) or 25 (PAL) in the Ease-In box.End Off Screen means that the text will simply continue up off the screen without stopping at any point.However, for me, I like the copyright notice and any logo that I may have added to stop at the end of the roll and wait for a while before the title ends. To do this, we need to use both the Ease-Out and the Postroll functions.Ease-OutOver what time would you like your title to slow down to a complete stop?I usually choose 2 seconds for this which would mean adding 60 (NTSC) or 50 (PAL) into this box.PostrollHow long do you want this title to stay still for at the end of your title roll?If you have an important notice or a copyright notice or a logo at the end you probably want to have it stay on screen for at least 3 seconds if not more. So in the Postroll box I would type 90 (NTSC) or 75 (PAL).So, a typical set up for the title starting off the bottom of the screen, then scrolling up and slowing down to a stop and waiting on screen for 3 seconds would look like this:Once you’ve made your choices, click OK and then shut down the title creation window. The new rolling title is now sitting in your project panel waiting to be added to your timeline like any other asset.Rolling Title SpeedNow, the speed of your title – how fast it actually scrolls up the screen – is completely in your hands. You can trim the title in the normal way by adjusting the clip length.Trimming the TitleHowever, you must bear something in mind…You have already specified that the title needs 5 seconds to slow down and stop on screen because we chose 2 seconds for ease-out and 3 seconds for postroll.This means that if the title is only 5 seconds long on your timeline that all the names will go through so fast you won’t even notice them before the titles slow down and stop! So, trim the length of your title out to the point whereby the names scroll up at the speed you want them to scroll up. You may need 20 – 50 seconds for even a small number of names – so try it out. Trim and have a look to make sure it’s what you want.Lastly, a couple of quick tips for rolling titles in Premiere Pro:
Essential Reading! Get my 3rd book: Eat Their Lunch “The first ever playbook for B2B salespeople on how to win clients and customers who are already being serviced by your competition.” Buy Now After your responsibility to develop yourself personally and professionally, your next greatest responsibility is to your relationships. You have to keep track of your relationships, and when you interact with the most important people in your life, you need an agenda.I’m a huge proponent using lists to manage your tasks. Or, if you need something more sophisticated, task management software. Lists and task managers that help you to keep track of all the commitments that you make.One of the most important ways to make lists is by context. This is a GTD concept where you keep a list by the location where you can do the work. For example your office is a context; there is some work you need to do that requires you be at your office (although that list seems to be shrinking dramatically for most of us). Your telephone is a context. The office in your home is a context. I’ve got my local drugstore and my grocery stores as context lists, too. When I’m in any of the locations I have listed as a context, I have a list of all the things I need to do while I’m there.But the most important context lists that I have developed is a list of people that I communicate with most frequently. High on this list are my clients. You can’t have a conversation with your client without them being there; in my mind, that makes individual people a context of their own. I have a context for each of my client’s names, and anytime something comes to mind for which I need to speak to that client, I capture it on their list. It doesn’t matter how big the idea is, how important the idea is, or how insignificant the idea is, if I’m thinking about it, I capture it.Whenever I speak with or meet with a client I’ve got an agenda in front of me. I have all the issues and ideas that I want to speak to them about in one view. This helps both of us use our limited time more effectively.Make a list of the people you need to communicate with most frequently. Maybe it’s your sales manager. Maybe it’s your clients. Maybe even want to put some personal relationships on a context and include your spouse or your kids. As you go through the week and ideas come to mind, add them to each person’s list. This is much faster and much more effective than making 10 individual phone calls, one for each time something pops in your head.If what you need to talk to your client about is urgent, by all means, call them immediately. But most of the things aren’t urgent,. The context list by relationship ensures that you have a placeholder for when you do get your client on the telephone.
Under pressure from the sports fraternity and the political class, the Delhi University on Friday decided to promote India Under-19 cricket team captain Unmukt Chand to the second year of his BA course.Unmukt, the star performer of the junior team that won the World Cup earlier this month, had been barred from writing his exam by St Stephen’s College because he didn’t have enough attendance. The college refused to consider Unmukt as a special case citing university rules and denied him entry into the second year of his course.The decision was heavily criticised by people and fans across the board, including India senior team captain MS Dhoni, Union Sports Minister Ajay Maken and Telecom Minister Kapil Sibal.Both Congress leaders spoke to the college principal and senior DU officials after which the university decided to relax its rules.DU vice-chacellor Dinesh Singh said: “Unmukt can continue his course. He will move to the second year.”Unmukt captained the Indian colts to a title triumph at the ICC Under-19 World Cup in Australia earlier this month. In fact, he hit a crucial century in the final against the hosts.
Earlier this week, five-star outside linebacker recruit Lyndell Wilson, who 247 Sports has ranked as the top player in the state of Alabama, announced his top seven teams on Twitter. USC was among the programs, and it looks like the Trojans are trying to take full advantage.Saturday, Lyndell tweeted out a photo of a dozen business cards he claims he was given by USC. The cards read that Wilson is the President and CEO of his own company, Lyndell Mack Wilson Inc. It’s a recruiting tactic we haven’t yet seen before.Wilson deleted the tweet shortly after posting it. We’re not sure if that means it’s potentially some sort of NCAA violation, or if he just didn’t want his address circulating the Internet. Ironically, under NCAA rules, Wilson can’t start a company and profit off of his likeness until he leaves school. Still, this is pretty cool.
A walk-on quarterback recently added to LSU’s roster is probably the most-appropriately named player in the history of the program. Meet Tiger Scheyd, a 6-foot, 179-pound redshirt freshman QB who became a member of Les Miles’ program this spring. Scheyd is surely deserving of his spot on the roster, but even if he’s not, his first name alone is reason enough to become a member of the Tigers.

After one of the most astonishing score lines in the history of the World Cup on Tuesday — Germany 7, Brazil 1 — nothing that happens in Sunday’s World Cup final would be a total surprise. But we do have estimates of the most likely final scores for the game.Germany is a 63 percent favorite to defeat Argentina, according to the FiveThirtyEight forecast. Argentina had a slightly higher Soccer Power Index (SPI) rating when the tournament began, but Germany has seen its rating rise, particularly after its thrashing of Brazil, and it now ranks No. 1 by some margin. Betting lines also have Germany favored.The SPI match predictor allows us to predict the number of goals scored and allowed for each club. It calls for 1.7 goals by Germany and 1.2 by Argentina.There are a couple of problems with this — for one thing, a team cannot score seven-tenths of a goal. So the match predictor uses a version of a Poisson distribution, which calculates the probability of the teams finishing with any whole-number score. For example, if Germany scores an average of 1.7 goals, how often does it score exactly two goals or exactly three goals? That’s what a Poisson distribution does.Another issue is that the match predictor is calibrated on the basis of 90-minute matches when knockout-round games can go to extra time. To account for extra-time results, we ran an additional Poisson regression based on the results of extra-time games in major international tournaments since 2005. (In geek speak, we’re nesting a Poisson distribution within another Poisson distribution.) All of that produces the following heat map:Read left to right for Germany’s score and top to bottom for Argentina’s. Boxes in which the score is still tied after extra time represent cases where the game goes to penalty kicks (there is about a 14 percent chance of this happening). The 10 most probable scores are as follows:Germany 2, Argentina 1Germany 1, Argentina 0Argentina 2, Germany 1Germany 2, Argentina 0Argentina 1, Germany 0Germany 3, Argentina 11-1 draw (game goes to penalties)Germany 3, Argentina 2Germany 3, Argentina 0Argentina 2, Germany 0What are the odds of another 7-1 scoreline? The model says there is only about a 0.06 percent probability of such a score favoring Germany (about one chance in 1,600). There’s even less of a chance — more than 10,000-to-1 against — of the same score favoring Argentina.But these figures may underestimate the chance of astonishingly lopsided results. The mathematical basis for the Poisson distribution is the assumption of independent trials. This is a little inexact (it describes a special case of a Poisson distribution called a binomial distribution), but a Poisson distribution is treating a soccer game something like this:Suppose we expect Germany to score 1.7 goals on average in a 90-minute game against Argentina. That translates into about a 2 percent probability (1 chance in 50) of scoring a goal in a given minute of play.So we can run an experiment where we randomly draw ping-pong balls from a set of 90 lottery machines, one representing each minute of the game. In each machine, there are 50 balls, one labeled GOAL! and 49 blanks. The probability of drawing a GOAL! from one machine doesn’t affect what happens with the next one. (This is the assumption of independent trials.) After we’ve drawn balls from all 90 machines, we count the number of GOAL! balls. This represents how often Germany scored in the game.We can repeat the experiment a bunch of times. Most commonly, we’ll wind up with something like one or two GOAL! balls. But other times we’ll have drawn zero or four or six. The relative frequency of these outcomes represents the Poisson distribution for Germany’s score.As strange as this experiment might seem, it isn’t a bad mathematical approximation of a soccer game. And for the most part, Poisson distributions do a good job of modeling real-world soccer scores.But there are some complications. For instance, we may have some estimate of how the absences of Neymar and Thiago Silva might affect Germany’s chances of scoring against Brazil. But there is some uncertainty around that: Maybe Brazil plays more fluidly when it isn’t waiting around for Neymar to do something, or maybe it breaks down. This is equivalent to not knowing exactly how many GOAL! balls and blanks there are in the ping-pong machines. This uncertainty will tend to slightly increase the number of extreme outcomes (Germany scoring zero goals or a lot of goals) that we observe in the real world.Another issue is that the texture of play in soccer depends to some extent on the scoreline. Play is usually tighter and more conservative in a drawn game and then opens up once the tie is broken. As a result, standard Poisson distributions slightly underestimate the chance of draws and of some wild scores, such as 5-2. (The variant of the Poisson distribution that we use is meant to address this problem.)For the most part in sports, these complications are not worth worrying about. There are cases where a Poisson distribution or a normal distribution isn’t perfect — normal distributions seem to slightly underestimate the number of extreme outlier scores in sports — but they usually hold up reasonably well. Nobody gets hurt when you say that Germany has only a 1-in-4,000 chance of winning by six goals when it actually had a 1-in-400 chance.But real-world distributions are often slightly fat-tailed, meaning that extreme outliers happen more often than the normal distribution predicts. And — outside the sports world — using the wrong model can cause real problems, underestimating the chance of an earthquake or a financial crisis.
