One of their premade templates is for YouTube channel art, which shows you a bunch of different template layouts you can use as a starting point. If you want to make a banner yourself but don’t want to go through the hassle of putting it together from scratch with a PSD template, you can use one of several banner creators.Ĭanva is one of my go-to recommendations for basically any kind of social media graphic design. If you don’t want to pay someone for a straight-up banner, though, there are other options. It’s the same way you see a lot of video intros that all look basically the same they’re pre-rendered videos with just customized logos slapped in on the end. A lot of Fiverr workers will be using templates they have found or developed, so while your banner will be relatively unique, it isn’t guaranteed to be totally unique. You can get YouTube channel art on Fiverr for anywhere from $5 to $50, depending on how unique you want the art to be. Since you’re unlikely to need all of that when you’re just looking for channel art, you’ll probably be able to get something relatively cheap.Īt the low end, well, this is one of the few things Fiverr is good for. Don’t let that scare you, though prices like those tend to include a lot of additional consulting, video SEO, channel optimizations, and even full channel management. At a casual glance at YouTube channel graphic design, you’ll see results ranging from $30 to $150 per hour. I recommend setting aside a modest budget for your branding assets, but your budget is really up to you.Īt the middle of the road, you can go to a site like Upwork to hire a freelancer. A lot of artists are willing to make simple banners and other such commissions, as they’re not too difficult to create and they can make a good chunk of change. On the more expensive end of freelancers, you can hire graphic designers from their portfolio pages. Why bother with a template when you can hire someone who knows what they’re doing already? Paid Bannersīefore I get into all of the various other options you have for DIY methods, I have to mention the fact that you can always just go buy a completed banner and not have to do the work yourself. ![]() There’s a tutorial video that accompanies the link above for the template, which will do a decent job of explaining what I mean. The same goes for the small area above and below the central safe zone. Content too far to the left or right of the center of your banner will be cropped out for many users, so don’t put anything essential there. This is important information going forward, because it helps guide your ability to create a banner of your own. For example, if a user is browsing on mobile, they’ll only see the smaller section on your channel page rather than the full banner. The light zone within the crop zone is what shows up on smaller versions of your channel page. ![]() If your image isn’t the appropriate size for a banner, the crop zone is the appropriate aspect ratio to show you what will actually show up in your banner. What is a safe zone for a YouTube banner? Well, when you go to upload a picture to YouTube for your banner, you see the full picture, a “crop” zone, and a light zone within the crop zone. This free download is aimed for PhotoShop users it’s basically a file of the appropriate size, with guidelines for the narrower “safe zone” in the middle. For those of us who aren’t graphic designers, though, where can you find templates or creators to help make a banner?įirst up, you can find a blank template for a YouTube banner here. You can do just about anything with your banner.

If the surface to be plastered is very uneven, three coats of plaster are applied where the first coat, scratch or dash coat, is applied for a smooth finish. If the thickness of the plaster is more than 15 mm or when you need a finer finish, two coats of plaster are required. For inner walls, a single coat of plaster is generally sufficient to achieve the desired finish. The number of plaster coats applied varies according to the requirement. ![]() Because there are many advantages of PPC cement over OPC cement. PPC cement is preferred in place of OPC-grade cement for plastering. Generally, OPC 43 and OPC 53-grade cement is mixed with sand (the fine aggregate) in different proportions hence, this plaster is also called as the cement-sand plaster. What is Cement Plaster?Ĭement plaster is a homogenous mixture of Portland cement, fine aggregates, and water. In this article, you will find brief information pertaining to cement plaster. Nowadays, cement plaster is mostly used in plastering the walls of a house. The plastic material or mortar used in the process is essentially a mixture of various building materials such as cement, lime, gypsum, fine aggregates (sand), and water. It protects the walls from rain and other environmental factors that could damage the structure. ![]() Plastering also provides a satisfactory base for painting, distempering, white washing, or colour washing. ![]() A coat of plaster can conceal uneven surfaces, making your walls look even, smooth, clean.

For some time now, we have had at our disposal scientifically valid assessments to predict and avoid managerial and leadership incompetence. The good news is that science has found a way to combat this problem. Many competent men are also overlooked for leadership roles because they don’t match our flawed leadership archetypes - meaning, they are perceived as “not masculine enough,” or fail to display the very attributes that make leaders less effective. If the future of leadership were more meritocratic, and managers selected leaders on the basis of their talent and potential rather than Machiavellian self-promotion, reckless risk taking, or narcissistic delusions, we would not just end up with more women leaders, but also with better leaders. Overconfidence is the natural result of privilege. This is partly for biological reasons - gender differences in impulsivity, dominance, and aggressiveness appear in all cultures and from a very early age - but also for cultural reasons. Although it is true that all of us are generally overconfident, men tend to be more overconfident (and arrogant) than women. The one main advantage men have over women when it comes to being picked for these roles is our human tendency to equate hubris and arrogance to talent. To start, those responsible for judging leadership candidates need to improve their ability to distinguish between confidence and competence. Of course, from a fairness standpoint hiring managers could just make it easier for incompetent women to become leaders, but a much better alternative is to instead discriminate more widely against incompetent men, for they are currently overrepresented in such roles. This applies equally to both genders, but for some reason we seem less preoccupied with combating incompetence in men than in women. It follows that the best way to create a positive one is to stop unethical people from rising to the top. Culture, whether good or bad, is just the product of the values and behaviors of our leaders. In an ideal world, those vetting candidates for leadership roles - in both politics and the business world - would make an effort to detect the potential signals of incompetence. But if this is true, who should be responsible for predicting, and ideally mitigating, incompetence in leaders? This means that we cannot realistically rely on those in power to measure their own capabilities. However, a great deal of research has shown that people who are really bad at something rate their own skills as highly as people who are really good at something - mainly due to a lack of self-awareness. Confidence (how good you think you are) is primarily beneficial when it is in sync with your competence (how good you actually are). Neither is it the case that we are better off when leaders have a great deal of confidence. Contrary to popular belief, most people are overconfident rather than underconfident. Few traits are as central to the anatomy of incompetent leadership as arrogance. Whatever way you look at it, the essence of incompetent leadership is easy to define: it is a function of the detrimental effects a leader has on their subordinates, followers, or organization. When I first made this point seven years ago, a large number of people wondered about the meaning of incompetence, especially in connection to leadership. Incompetent leaders are the main reason for low levels of employee engagement, and the prevalent high levels of passive job seeking and self-employment. Consider that the economic impact of avoiding a toxic worker is two times higher than that of hiring a star performer. Whereas competent leaders cause high levels of trust, engagement, and productivity, incompetent ones result in anxious, alienated workers who practice counterproductive work behaviors and spread toxicity throughout the firm. If you want to understand why some companies have a toxic culture, underperform relative to their potential, and eventually collapse - look no further than the quality of their leadership teams. ![]() In this experiment, students will be asked to explain the model of light. Experiment 3 - Light Wave-Particle Duality To give them a starting point, provide the specific examples, i.e., what it would look like when you let sand pass through the double slits vs water, then ask what they expect to happen when they flash a laser. The idea of this experiment is that students start to form a model of the light’s behavior as a particle and as a wave.īefore setting up any of the experiments, ask the students what they are expecting to see when light goes through an obstacle such as the double slit, what a particle behavior should look like, what a wave behavior should look like, and finally, what light would look like. In the student’s guide, students are tasked with developing an experiment, following Young’s experiment, to see if they can determine whether light behaves as a particle or a wave. Stay at Home Experiments #1 / DIY Double Slit Experiment! Quantum Physics at Home Safetyĭo not point the laser at anyone, and do not look directly into the laser. We have found this the easiest and most reliable form of doing it.

Remove the rubber and separate the intertwined pieces of copper. Cut a piece of a cable that you don’t mind discarding. Laser pointer, any kind (red lasers work best because of its larger wavelength).Now it is time for you to check it out! Experiment Many other scientists throughout history have tested this concept with electrons, molecules, and atoms always seeing the same result. Therefore, he demonstrated that light can behave both as particle and wave. If he left exposure of the photo for long enough, the little points started forming the interference pattern. But when he dimmed the light to very low level, the photos were of little points, like particles hitting the screen. Initially he saw the same interference patter as Young. In 1909, Geofrey Taylor repeated Young’s experiment and took photos of the light coming out of the slits. In order to be sure, other scientists decided to explore the subject a bit further. So then, that’s it, right? Light is a wave! Yes, but… Confirming the hypothesis that light behaves as a wave. That is exactly what Young’s double-slit experiment showed. ![]() If instead of thinking of water waves now we think about light, then what we expect to see on the wall will be lines of bright light and lines with no light. Then you can imagine what happens when the paths of two troughs cross each other: they forma deeper trough. When the crest of waves created by rock A crosses the crest of waves created by rock B, then they form a taller crest. When the crests of waves created by rock A cross the troughs of waves created by rock B, they will cancel each other out. As the waves spread, we will see that the waves that originated from one rock will start to cross the path of the waves created by the other rock. If we throw a rock next to it, we will see that it also creates crests and troughs. If we throw a rock in the water, we see that it creates waves that have crests and troughs. Let’s go back to the ripples in the water. What he saw was what physicists now call an interference pattern. In this experiment, Young would shine a light source onto a screen that had two small slits close to one another to see the reflection of the light after passing through the slits in the wall behind it. But scientists could not agree if light behaves like a particle or a wave In 1801, Thomas Young, a British scientist, was convinced that light was a wave, and he designed his famous double-slit experiment. We can see how a rock behaves differently from a wave. When you throw a rock in the water, you are transferring some energy of the movement of the rock into the water, which causes the water to move around to disperse that energy. In physics, waves are described as the spread of the disturbance or perturbation of something, often energy. Have you noticed what happens when you throw a rock in the water? It makes waves that spread in a ring and grow as they move outward. On the other hand, we have things that can be at different places at the same time, such as waves. We can say that these objects behave like a particle, which is a tiny object that is characterized by only being in one place at a time. In the world we experience every day, we see that objects, like a chair or a rock, can only be in one place at one time. The concept behind how light travels and behaves has been one of physics’ greatest mysteries. |
