When seeking a natural detergen t, you might come across recommendations of stripping clothes with baking soda and vinegar, but scientifically speaking, this is very ineffective. This common mistake might lead you to wonder if there is any organic laundry detergent you could use as a substitute for l aundry stripping and daily use.Ĭan You Use Natural Detergent Laundry for Laundry Stripping ? As CNN goes on to say, the need for laundry stripping is ironically caused in part by people using too many chemical-filled detergents. Krietsch also notes that the color change can partially be attributed to the dye seeping out of the fabric and the caked-up detergent that was holding onto dirt. Rather, it is from the minerals in the hard water-and those previously embedded in the clothes-reacting with the excess detergent dunked into the tub-and the soap previously built-up on the clothes. Thus, when you see videos of people stripping their laundry, the striking color change of the tub water is not due to the inherent dirtiness of the fabrics being soaked. They stated that most residue on clothing is from previous overuse of detergent and fabric softener. CNN interviewed Jennifer Ahoni, a senior scientist at a detergent company, and Leigh Krietsch Boerner, a journalist with a Ph.D. The residue makes clothing stiff and can cause fabric fibers to break down over time.įurther causing laundry complications, most people use an excess of detergent when washing clothing regularly and, ironically, when trying to strip laundry of its buildup. They said in a comment, "yes, I'm aware my water is already yellow we have hard water." In addition to occasionally being cloudy, hard water deposits minerals onto laundry, leaving a residue behind. N otice in this stripping laundry recipe video that the water in this user's tub is discolored even before adding chemicals. In the United States, 85% of citizens' homes have hard water, meaning that the water contains a high concentration of minerals, usually calcium and magnesium. However, the opaque color is actually due to a reaction between hard water and detergent. What is the Science Behind the Water Becoming Cloudy?Īt first glance, it would be reasonable to infer that the mucky water from laundry stripping is caused by the fabrics having been previously soiled. You might be surprised to learn that the color change isn't caused by the original dirt on the clothes, but rather a more complicated chemical reaction. In watching #laundrystripping videos or stripping your own laundry at home, you will see that these laundry stripping ingredients cause a stark change to the color of the water, even when laundry stripping with baking soda or detergent. If you would like a more exact method for stripping clothes, Erica Gremminger in her video provides this popular clothes stripping recipe :Īfter hearing that most people are stripping clothes with borax, you might hesitate in following through with these recipes, as many sources such as Medical News Today report that even though borax is a naturally-occurring salt, "a person should strongly consider not using products that contain borax when possible." If you are curious if there is a laundry stripping recipe without borax, Laundry Detergent Ideas says instead of borax laundry stripping, you can use both a ½ cup of laundry detergent and ½ cup of washing soda for each gallon of hot water. At least on TikTok, many laundry stripping recipes are just an eyeballed hodgepodge of stripping laundry with borax and detergent, sometimes with washing soda, oxygenated bleach, or fabric softener. Though video creators vary in their recipes, laundry stripping TikTok videos all share a common process-fill your bathtub with water, dump in enough chemicals that would make an apothecary blush, and let your clothes soak for approximately five hours. What is the Best Laundry Stripping Recipe ? Read below as we uncover the surprising science behind the trend. What has sparked people's horror (and fascination) with TikTok laundry stripping is the almost-instant transformation of the bathtub water from crystal-clear to a murky brown when the clothes are added, caused by the crud being purged from the laundry, or so it seems.Īfter learning about or seeing firsthand the plethora of viral videos covering everything from stripping towels to stripping sheets, you might be asking yourself how stripping laundry is done correctly, what sort of chemical reaction is actually taking place in the tub, and if there are any better alternatives for deep-cleaning your laundry. Have you been on the "cleaning side" of TikTok (or #CleanTok, as some affectionately call it) or Facebook Watch? If so, you were bound to have encountered videos of "l aundry stripping ," where people soak dirty fabrics in their bathtubs mixed with a flurry of chemicals to "strip" the grime the textiles had accumulated over time.

To an observer on another spaceship moving at a different speed, time would move slower on the spaceship traveling at near the speed of light, and would theoretically stop if the spaceship could actually reach the speed of light. A common example depicting this involves a spaceship moving near the speed of light. Essentially, for observers within different inertial frames of reference (different relative velocities), both the shape of space as well as the measurement of time simultaneously change due to the invariance of the speed of light – a view vastly different from Newton's. Einstein posited that the speed of light, c, in vacuum, is the same for all observers, independent of the motion of the light source, and relates distances measured in space with distances measured in time. Unlike Newton, who believed that time moved identically for all observers regardless of the frame of reference, Einstein, building on Leibniz's view that time is relative, introduced the idea of spacetime as connected, rather than separate concepts of space and time. Michelson, Hendrik Lorentz, and Henri Poincare among others, contributed to what would ultimately transform theoretical physics and astronomy, the scientist credited with compiling and describing the theory of relativity and the Lorenz Transformation was Albert Einstein. While many scientists, including Ernst Mach, Albert A. Despite Leibniz's efforts, this Newtonian concept of physics remained prevalent for nearly two centuries. He argued that absolute space was necessary in order to account for cases where a relationalist perspective could not fully explain an object's rotation and acceleration. Since this example showed that the concavity of the water was not based on an interaction between the bucket and the water, Newton claimed that the water was rotating in relation to a third entity, absolute space. If the bucket's rotation is then stopped, the water remains concave during the period it continues to spin. In this argument, water in a bucket hanging stationary from a rope begins with a flat surface, which becomes concave as the water and bucket are made to spin. One of the prominent arguments that arose from the correspondence between Newton's spokesman Samuel Clarke and Leibniz is referred to as the bucket argument, or Newton's bucket. It is simply the way in which humans subjectively perceive and sequence the objects, events, and experiences accumulated throughout their lifetimes. Within this argument, known as relational time, time itself cannot be measured. According to Leibniz, time is nothing more than a concept similar to space and numbers that allows humans to compare and sequence events. Newton's realist view is sometimes referred to as Newtonian time.Ĭontrary to Newton's assertions, Leibniz believed that time only makes sense in the presence of objects with which it can interact. Relative time on the other hand, is what humans actually perceive and is a measurement of "duration" through the motion of objects, such as the sun and the moon. He argued that absolute time exists and flows without any regard to external factors, and called this "duration." According to Newton, absolute time can only be understood mathematically, since it is imperceptible. In Newton's Philosophiæ Naturalis Principia Mathematica, Newton tackled the concepts of space and time as absolutes. Aristotle's view is solely one amongst many in the discussion of time, the most controversial of which began with Sir Isaac Newton, and Gottfried Leibniz. Interestingly, he was also one of the first people, if not the first person, to frame the idea that time existing of two different kinds of non-existence makes time existing at all, questionable. He also believed that time was infinite and continuous, and that the universe always did, and always will exist. One of the earlier views was presented by the ancient Greek philosopher Aristotle (384-322 BC), who defined time as "a number of movement in respect of the before and after." Essentially, Aristotle's view of time defined it as a measurement of change requiring the existence of some kind of motion or change. There exist various concepts of time that have been postulated by different philosophers and scientists over an extensive period of human history. Oct., Dec.-31 daysįeb.-28 days for a common year and 29 days for a leap yearĢ4 hours or 1,440 minutes or 86,400 seconds The following table shows some common units of time. However, due to how time is defined, there exist differences in how calculations must be computed when compared to decimal numbers. Like other numbers, time can be added or subtracted. Pay attention to which version of Bluetooth your speaker uses. ‘Not all Bluetooth speakers offer this feature, but it can be a great way of creating a more hi-fi-like’ sound.’ Specifications ‘Here, you buy two speakers of the same model and wirelessly link them, creating a stereo effect,’ Powell says. One function worth your attention is the ability to create a stereo pair. But pay close attention to the manufacturer’s quoted battery life if you’re using it far from a power source.’ Pairing ‘The sound can get lost in outdoor settings,’ Powell says, ‘so if it’s for garden use, consider a larger unit that can fill the space. Work out your needs – think, indoor, outdoor, portability, durability and the like.’ How to choose the best Bluetooth speaker for you Power Compare it to buying a car: you wouldn’t expect an Alfa Romeo Spider (lovely though it is) to fit a family of five and the dog, so don’t expect a teeny Bluetooth speaker to fill a big space with sound. He says, ‘The best Bluetooth speakers fit your needs, working around you, not the opposite. So what makes the best Bluetooth speaker?

Now they’re far better performers and Bluetooth is an essential feature of the best wireless speakers – particularly for outdoor settings. Pairing and unpairing them with phones and MP3 players was a grim chore, only to be undertaken when absolutely unavoidable. Just a decade ago, even the best portable speakers tended to sound fairly awful and had very limited range. But Harald could hardly fail to be impressed by the variety and quality of the best Bluetooth speakers now on offer. When King Harald Bluetooth, son of Gorm The Old, died in the year 986 he almost certainly didn’t imagine that more than a thousand years later hundreds of millions of household devices would bear his name: Bluetooth is so called because it ‘unites’ gadgets in the same way Harald united Denmark.

Instagram Story Views | Female Profilesīu圜 is a very reliable partner for many years when it comes to social media projects and their components. There are two parts to the concept, namely ‘timely’ and ‘fashion’. It is not a legally binding term, given the vagueness of the expression, but does imply the need for due diligence and cognisance of a time frame in which to deliver results. Time is important but attitude even more so They might have loud hailers, and shout, ‘A tsunami is coming! A tsunami is coming! Get out the building now and head for the top of the hill!’ Management would probably not urge their guests to leave the hotel, ‘in a timely fashion’. In the moments before the disaster, however, the term would not have been effective. The occupants of the hotel received the warning of the tsunami in a timely fashion and were therefore able to evacuate the building and reach high ground before disaster struck. The use of the phrase implies an agreement between two people, usually of different ranks, about a task that will take a period of time, and may be complex.įor example, it would be used when requesting that the catering for a party be delivered on time, but not for a single cup of tea on returning home. If a senior member of staff wanted a junior member of staff to deliver results quickly, they would employ this phrase. The term arose around the mid-1900s during the era that saw the rise of corporate management. “In a timely manner” is basically a formal, but polite way of saying, ‘hurry up’, or ‘I need this task completed quickly’. What is the meaning of “in a timely manner”? In the 21 st century, we would more likely speak of delivering, ‘to a given standard, on time and within budget’. It has its origins in the emergence of bureaucracy, and has been replaced by terms more commonly used these days in project management. The phrase “in a timely manner” conjures up images of a bygone era when time seemed to move more slowly.

This is a tuning problem, and whether the index is valuable is going to depend heavily on the size and distribution of the data.Īdditionally, there is very little gain in terms of space if you still need another index for the name IS NULL rows. If your table is very large, even eliminating 50% of the rows might be worth it. If however, only 1% of rows have name IS NOT NULL, then this represents huge savings as PostgreSQL can ignore most of the table for your query. E.g., if 99% of the rows have name IS NOT NULL, the index isn't buying you anything over just letting a full table scan happen in fact, it would be less efficient (as notes) since it would require extra disk reads. Note that you'll only see benefits from this index if it can allow PostgreSQL to ignore a large amount of rows when executing your query. (An unordered index would require a full index scan just to delete.) In light of that fact, any gains from an unordered index would be usually be outweighed by the detriments, so the development effort isn't justified.įor space and performance, though, if you want a highly selective index for efficiency, you can include a WHERE clause on an index, as noted in the fine manual: CREATE INDEX ON my_table (name) WHERE name IS NOT NULL A B-Tree index is preferable because deletes from it will be faster than some kind of "unordered" index (for lack of a better term). I'm interpreting you claim that it's "overkill" in two ways: in terms of complexity (using a B-Tree instead of just a list) and space/performance.įor complexity, it's not overkill. |
