Darwin-Loving Democrat Takes Helm of AAAS

first_imgFormer Congressman Rush D. Holt gave his inaugural editorial in Science Magazine on Feb. 20.Nature had called it a bad move that would only deepen the entrenched political divide. In December, Daniel Sarewitz said that science should stay out of partisan politics (see 12/07/14):Two weeks after US voters installed a Republican majority in the Senate and expanded the Republican majority in the House of Representatives, the American Association for the Advancement of Science (AAAS) made its own political statement: it named a former Democratic member of Congress as its new chief.Once, these events might have been unrelated. But in today’s poisonous partisan atmosphere, the AAAS’s choice of Rush Holt, a physicist and political centrist just finishing a 16-year stint in Congress, looks every bit as political as the election itself.Now, Rush D. Holt is leader of the AAAS and publisher of Science Magazine. His opening editorial, “Why science? Why the AAAS?” reeks of scientism:Among the various ways of thinking and knowing about the universe and ourselves, science is special. Asking questions that can be answered empirically and engaging in open communication so that others can collectively review and verify possible answers lead to the most reliable knowledge—a knowledge that is powerfully applicable in daily life. Science is, as physician and essayist Lewis Thomas wrote, the “shrewdest maneuver” for discovering the world. This grand and clever enterprise, while surely not removing all worldly woes, brings beauty, wonderfully fulfilling intellectual pleasure, and cultural enrichment. It can lead to improved human interaction, more constructive commerce, and a better quality of life. Science helps bring what I think is a deep human need—a sense of progress.The problem is that the same claims can be made of theology, or of any other social enterprise performed with integrity and clarity of thought. At best, science only partially fulfills these benefits; at worst, it can lead to decades or even centuries of regress. “Science” itself—contrary to Holt’s simplistic description of it—is far too big a tent for each sub-branch to score equally well (compare scandal-ridden evolutionary psychology, empirically-challenged string theory, or fringe sciences like political science, economics, and cosmology where some wild and wacky ideas conflict with other wild and wacky ideas). Scientism is not an empirical discovery by science. It is a statement of philosophy about science. Holt knows a lot about physics and fund-raising for science, but it is not clear he knows much philosophy of science.Holt holds out an olive branch to those outside his cloister:The organization will build its publications and communications ability to meet the modern needs of the scientific community and the general public. AAAS will enhance its programs in public affairs, education, law, and international relations, and continue to explore constructive relationships between science and religion, art, history, and other disciplines. I am committed to raising the necessary resources to do these things. Especially, AAAS intends to remain the world’s most effective advocate for science.Some theologians could well question his sincerity. In 2013, according to the Huffington Post, Holt issued a resolution in Congress calling for a celebration of Darwin Day (see 2/12/15):“Charles Darwin [is] a worthy symbol on which to celebrate the achievements of reason, science, and the advancement of human knowledge,” Holt wrote in the resolution, which promotes evolution and warns against the “teaching of creationism.”In a statement from the American Humanist Association, Holt lauded Darwin’s legacy, calling him one of our “greatest thinkers.”“Only very rarely in human history has someone uncovered a fundamentally new way of thinking about the world -– an insight so revolutionary that it has made possible further creative and explanatory thinking,” Holt said. “Without Charles Darwin, our modern understandings of biology, ecology, genetics, and medicine would be utterly impossible,* and our comprehension of the world around us would be vastly poorer.“The NCSE, of course, was thrilled. If this represents Holt’s view of exploring “constructive relationships between  science and religion,” then artists, historians and members of other disciplines can well be afraid. Holt’s view of a constructive relationship may resemble the compromise between a hungry bear and a freezing man: both got what they wanted: the bear, a meal, and the man, a fur coat. Judging from his scientism, Rush Holt’s idea of a constructive relationship with any other discipline would be for the AAAS to swallow it.*As for whether Darwinism increases understanding, see the Stuff Happens Law in the Darwin Dictionary. As for Darwinian medicine, see 12/16/11 and its embedded links, and also a post on Evolution News & Views by Dr. Michael Egnor. As for ecology, genetics or any other sub-discipline of biology, Darwin’s contributions are not without controversy.So here we go again. This is like ISIS replacing Al-Qaeda. Expect a big order of pom-poms for Darwin cheerleaders and demands for budget-busting increases for Whatever Big Science Desires. Given the growing dissatisfaction with Darwinist reductionism (even among scientists), there might be a bright side. This could be scientism’s last hurrah before it implodes. We must keep the heat on. (Visited 13 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Using the Track Select Forward Tool in DaVinci Resolve 15

first_imgLearning a new application can mean spending hours stumped by usability issues. Here’s one we found in Resolve — and how to fix it.Every so often, we run across an issue that doesn’t have an apparent answer, partly because we’re not too sure what’s causing the problem. There’s one issue in Resolve that, when I was new to the platform, boggled me for hours, and that’s selecting multiple clips at once from the playheads position using the track select forward shortcut.If familiar with Premiere Pro, you’re likely familiar with this button:It’s the handy Track Select Tool, which allows you to move the contents of an entire track forward from the position of the playhead. You can also move multiple tracks by holding shift and selecting a different track. It’s an efficient way of moving multiple clips on numerous tracks forward or backward, without selecting all clips. As is the case in Resolve, if we were to select all clips (Ctrl+A) in the image below, we would be unable to move the clips back because track one already has clips that reach the start of the timeline, which acts as a wall.However, if we were to track-select Video 2 and Audio 1 and 2, we could then move all clips back to the desired position.We could, in theory, also hold shift and highlight the desired clips across the tracks to move them backward or forward. However, if you have a long timeline with multiple clips, that’s a recipe for disaster. I could happily sing the praises of Resolve’s user interface and design mechanics all day long. It’s very user-friendly, but every so often, I do run into a feature that could perform better. Selecting clips forward and backward is the heel today.In Resolve, we don’t exactly have a tool icon to select, nor is it available using the trim tool, but you can perform the operation by using a keyboard shortcut — which is Y or Ctrl+Y to select all clips back from the playhead position. However, as you can see in the GIF below, look what happens when I hit Y and Ctrl+Y after selecting the track region I want to move forward:The clips on the track above become selected, and the clips on track one, the track I selected, have been omitted from the process. This is because the track above is currently the designated video track, meaning if I were to insert a clip from the source viewer, it would appear on the secondary track. We can see that it’s the destination track because of the orange square active on the track header. So, even though I have selected track one because it’s not the active destination track, the select clips forward function does not work the way I need it to. To move the clips forward for the first video track, which is confusingly also called V1, you have to change the destination track — which you can do so by selecting the V1 button.A secondary issue when using these shortcuts is when you want to move clips forward from all tracks, which you do by pressing Alt+Y, or Ctrl+ALT+Y to select all tracks backward from your position. One would think that as you’re selecting all the tracks, there wouldn’t be an issue with having a designated video track as you’re selecting multiple. Yet, as you can see below, when hitting Alt+Y, only the clips from the one video track are selected.Why is this? Well, unlike having an active video track destination, this is now a result of autoselect (if you are unfamiliar with autoselect, you can read about that feature here). In the example, you can see that I don’t have autoselect active on any of the tracks. Therefore, to track-select all tracks, I need to activate autoselect. At first, this seems like a hindrance. However, it was designed this way — if you need to select all tracks except two, you can omit those two tracks by deselecting autoselect.So, the tl;dr:To change the track that you want to use the track select tool on, you have to change the designated video or audio track.To select multiple tracks, you have to turn autoselect on.
